* AnticlimaxBoss: In the Barbarossa campaign's last scenario, ''The Emperor Sleeping'', after fighting your way through Damascus and the Saracen's camp, all spawning powerful units at will, you end up in a fortified but soldierless Jerusalem.
* AnnoyingVideoGameHelper: In the vanilla version, Mangonels/Onagers will ''not'' stop to attack an enemy unit within their line of sight if one of your other units can be damaged.
* AwardSnub: Many gamers say that this game should have won the 2016 "Test of Time" Steam Award, when it was the only nominee that was older than a decade at time,[[note]]as least, in terms of when the original version was released; Steam has the ''HD Edition'' of the game, which was released in 2013[[/note]] while the winner (''VideoGame/TheElderScrollsVSkyrim'') was the ''youngest'' of the nominees[[note]]again, based on initial release[[/note]] at only a month over five years old.
* BetterThanCanon: An extensive community exists towards creating custom campaigns using the in game scenario editor, and to say that some of these have such effort and commitment put into them as to shame the official campaigns as released is an understatement. They can be found [[http://aok.heavengames.com/blacksmith/ here]].
* CasualCompetitiveConflict: Competitive players tend to ignore anything beyond ''The Conquerors''. The most common reasons being performance bugs on multiplayer in the HD versions and many changes that disrupts the well-established metagame for said expansion such as several TierInducedScrappy civilizations (both high-end and low-end of the trope) introduced in ''Forgotten Empires/The Forgotten'' and ''The African Kingdoms'', as well as biased changes to the existing civilisations. Not to mention the fact that Ensemble Studios had nothing to do with the HD version and its expansions.
* ComplacentGamingSyndrome:
** Expect to see Deathmatch Hun only matches, and be criticized if you don't play Deathmatches as the Huns.
** Most people try to avert this by having all players mandatory pick Random for civ selection, [[FakeBalance but this has its own problems.]]
** The very popular Castle Blood Arena (CBA), there are only 5 non-faction specific units worth producing in late game. Arbalests, Heavy Cavalry Archers, Hand Cannoneers, Paladins, and Heavy Camels. Although Pikeman/Halberdiers can be situationally useful if fighting the Persians. The only reason to produce anything else is if you can't build any of those 5 units.
** Knight rushes are very popular since they are {{Lightning Bruiser}}s and can be trained as soon as players hit the Castle Age while their counters need to be upgraded first before they can even stand a chance against them. However, civilizations that lack Bloodlines (+20 HP for cavalry) will find this strategy to be less appealing.
* CriticalResearchFailure:
** In ''Age of Kings'':
*** The final scenario for the tutorial campaign (the Battle of Falkirk) portrays it as a siege, and implies that William Wallace survives to continue his war with the English. While they were probably trying to avoid the historical DownerEnding, they could've just as easily given Wallace a HeroicSacrifice. Alternatively:
*** The Battle of Falkirk should have had you playing as the English where you have to defeat William Wallace. It also should have been the second-to-last mission of the Tutorial campaign. The real final tutorial mission should have been the Battle of Bannockburn, where it reveals that the narrator of the tutorial campaign was Robert the Bruce.
** In ''The Conquerors'':
*** The religious building for the Mesoamericans are still called Monasteries, and the religious unit is still called "Monk". However, their monk actually uses a different skin than other monks, making them look like a {{Mayincatec}} priest. At least they got the blood on the stairs.
*** The Montezuma campaign repeats the popular myth that the Aztecs mistook the Spanish for gods.
*** In the El Cid campaign, El Cid was said to have been killed by an arrow and propped up on a horse in order to stop the truth from spreading. In reality, he died peacefully. This was probably done for the same or similar reasons as the Battle of Falkirk bit.
* EnsembleDarkhorse: For a very minor role in the first Genghis Khan level, Ornlu has gotten quite poular among the fanbase, enough for the developers to reference him in ''Age of Mythology'' and ''Age of Empires III''.
* EvenBetterSequel: While their [[VideoGame/AgeOfEmpiresI predecessor]] got a high rating of 83% at Metacritic, this game got a 92%.
* GermansLoveDavidHasselhoff: Age of Empires II has gotten some popularity in mainland China to the point there is actually a larger competitive scene than Europe and America. [[note]]Which is quite ironic since a lot of Age of Empires II fans in the west have used the Chinese tech tree of lacking gunpowder units and block printing as an example of blatant historical inaccuracy of the game[[/note]]
** According to Youtuber and streamer, [=ZeroEmpires=], Age of Empires II (as well as Age of Empires I) has a sizable fanbase in Vietnam, which makes the inclusion of the Vietnamese in ''Rise of the Rajas'' expansion to be seen as Crowning Moment of Heartwarming.
* GoodBadBugs:
** In the fourth Attila the Hun mission, you are tasked with destroying three major cities. Destroying the third spawns the massive Roman Army, a force of over a hundred top-tier units...unless you found and killed the placeholder unit on the map, which causes the army to be instantly defeated.
** In the fifth Saladin mission, "Jihad!", one of the three cities, Ascalon, is intended to attempt a Wonder victory. However, sometimes the AI for Ascalon bugs out and doesn't do anything. Given as how "Jihad!" is ThatOneLevel even without Ascalon going for the Wonder, this is immensely helpful.
** The in game scenario editor can do some interesting things with structures and terrain elements that shouldn't be possible. This has been abused ''thoroughly'' by the modding community creating custom campaigns.
** In the first scenario of the Attila the Hun campaign, it's possible to fire both the "Bleda getting killed in the boar hunt" and the "Attila fleeing the Hun camp" events if your timing is good. Because of the first event, the Huns will argue over whether Attila is a worthy leader or an honorless cur, but the second event will make all Hun units instantly join your side upon Bleda's death. This has the practical benefit of giving you Bleda's entire faction with minimal bloodshed. Another bug in the same scenario can occur if the player allies with the Scythians. While the Scythians will break their alliance with the Persians, the Persians don't always do the same and won't even bother to fight back as the Scythians slaughter their way through their base.
** In the fourth Sundjata scenario "Blood on The River Bank", a bug can cause Gbetos to be produced every second on one of your allies' Barracks, resulting in the player having a massive amount of infinitely-generated troops.
** In an early version of the game, in "The Crucible", the first Genghis Khan level, Genghis Khan -- an extremely strong and powerful hero with a Mangudai model -- could be converted to player control at the start, making it ridiculously easy.
* HilariousInHindsight: The original cover art featured a European king, a viking, and a samurai. Many years later, a MeleeATrois between knights, vikings, and samurai would take place in ''VideoGame/ForHonor''.
* ItsTheSameNowItSucks: While the Middle Eastern architecture set suits the Berbers, there's still the issue that ''6'' civs share the same set (Saracens, Turks, Persians, Byzantines, Indians (until ''Rise of the Rajas'', where they officially get a unique set) and the aforementioned Berbers).
* KonamiCode: There are more than [[https://www.gamefaqs.com/pc/63605-age-of-empires-ii-the-age-of-kings/cheats a dozen]] but "how do you turn this on" for [[ArmyOfTheAges a car with a machine gun]] is the most famous.
* MemeticLoser: While still a decent civ, the Chinese are often mocked for not having Hand Cannoneers and Bombard Cannons despite being credited for inventing gunpowder in real life. Some people even forget that they have access to Bombard Towers and Cannon Galleons because of this in addition to their unique technology, "Rocketry" (although it only boosts the damage for Chu Ko Nus and [[ScrappyWeapon Scorpions]] only). Some speculated that this is for gameplay balance purposes, as they are supposed to function as the JackOfAllTrades civilization.
* MemeticMutation:
** Ten elephants fit in the transport boat but eleven archers can't.
** "how do you turn this on".
* MostAnnoyingSound:
** The monk conversion noise, especially if it is successful.
** In the Saladin campaign, from Medina and Aqaba:
---> ''"Crusaders are attacking our trade routes!"''
** The "Under Attack" warning tone can also qualify, it's quite loud and plays on an interval of less than 5 seconds. Imagine hearing this for 10 minutes during a skirmish:
--> ''"Ding-Dong!" "You are being attacked by the British"''\\
''"Ding-Dong!" "You are being attacked by the Turks"''\\
''"Ding-Dong!" "You are being attacked by wild animals."''\\
"Arrrgggh! Shut up already!"
** The 'Shikkashikkashikka' that plays whenever one of your farms depletes. Apparently, even the developers found this annoying, and introduced the Farm Queue in the expansion.
** The "attacked by wild animals" sound as noted above is even worse than the "Under Attack" sound -- especially when you forgot to research Loom or the attacked villager is in low health.
** In games with an allied AI teammate:
---> ''wood sire!'', ''wood sire!'', ''wood sire!''
----> Ignoring it can mean leavening your ally defenceless to an enemy push with an unbalanced economy that can't support the troops they are trying to build, but helping them will often means watching the AI throw your tribute away on petards or building an armada of ships for senseless reasons.
* RescuedFromTheScrappyHeap:
** Scorpions. They're essentially giant crossbows on wheels that fire penetrating bolts that pass through enemies, and thus can hit a whole line of enemies all at once. What's the issue? ''Their damage''. In the original game, they had a base damage of ''7'', which gets reduced by pierce armor, meaning pretty much anything with upgraded armor can reduce it to ScratchDamage. Their dismal range, low mobility and poor health didn't help. Upgrading them to Heavy Scorpions, however, did give them a somewhat more respectable base damage of 16, and the later expansions raised their base damage to 12, making them at least somewhat situationally useful. The ''Rise of the Rajas'' expansion introduces the Khmer's team bonus of +1 range for Scorpions for their teammates while making their own Scorpions and Ballista Elephants fire extra projectiles with their Unique Tech, making massing Scorpions a viable option.
** In Water Maps, Fish Traps are rarely used by professional players despite the fact that there are lack of building space in water maps. This is because villagers gather food faster from Farms than Fishing Ship from Fish Traps. The HD expansions introduced [[http://ageofempires.wikia.com/wiki/Gillnets Gillnets]] that greatly improve the gather rathers for Fishing Ships, and in the ''Rise of the Rajas'' expansion, two of Malay's civilization bonuses not only makes Fishing Traps cheaper, but they provide unlimited food.
* ScrappyWeapon:
** Camels are usually avoided because they cost a lot of gold, yet are ''very'' frail. They die easily to building fire as they're classified as ships (which have a similar weakness) to differentiate themselves from Knights. This is one of the reasons why the Indians cannot utilize their camels prior to ''The African Kingdoms'' because their Knight line (one of the most powerful standard units in the Castle Age) is completely replaced by Camels, which due to the reasons above above cannot be used similarly to Knights.
** The Champion line and most of the infantry Unique Units (with the exception of Huskarls, every single Malian infantry, Shotel Warriors and Woad Raiders) rarely see use in competitive play due to being slow, requiring obscenely expensive upgrades that barely do anything and having many common weaknesses, namely the commonly-used archers, gunpowder units, knights and Onagers.
*** The Samurai, Teutonic Knights, and Jaguar Warriors can be an exception as well depending on the situation. Since the Samurai have bonus points against other unique units, TheTeutonicKnights are {{Mighty Glacier}}s that can obliterate almost any melee units that gets in their path thanks to their armor bonus, and the Jaguar Warriors slaughters other infantry and have a unique tech that gives them +4 attack points.
* SpiritualAdaptation:
** The William Wallace learning campaign could pretty much be considered ''Film/{{Braveheart}}: [[VideoGameAdaptation The Video Game]]''. The fact that ''Age of Kings'' was released four years after the movie certainly helps.
** The El Cid campaign is closer to the 1961 Creator/CharltonHeston [[Film/ElCid film]] than to the Medieval epic or the real guy's life.
* SurprisinglyImprovedSequel: The original was OK, the sequels are universally acclaimed.
* TheyWastedAPerfectlyGoodPlot: ''The African Kingdoms'' would have been a perfectly reasonable opportunity to incorporate the Vandals (one of the most notable Germanic enemies of the Romans, other than the Goths) into the game, seeing as they had ruled the North African kingdom of Carthage for a time, and they ''sacked'' Rome during that period. Surely, that would've been worth at least one scenario that was about them, right?
* TierInducedScrappy:
** Koreans, Saracens and Turks in open maps. All three of them have poor early-game and open maps make them susceptible to being rushed. This is inverted in closed maps (e.g. Black Forest) where they dominate due to the nature of the map itself and they have access to many [[MagikarpPower strong Imperial Age units]] and technology.
** Infantry Unique Units mostly range between extremely situational to completely useless with a few exceptions, but among civs that get them the Franks got it the worst. Despite being billed as the "Cavalry" civilization their only relevant cavalry bonus is extra HP for Knights (which becomes insignificant when many other civs get Bloodlines; which affects ''all'' mounted units). Their Unique Unit the Throwing Axeman is regarded as one of the worst as it is easily countered, has the strength of a ''Long Swordsman'' even when fully upgraded, short ranged and ended up slower than most infantry due to them lacking Squires. They also got overshadowed by other civilizations with better cavalry and bonuses such as the Spanish, Persians, Huns, Magyars and Berbers. ''The Forgotten'' noticed this and buffed the Franks by making their foragers work faster, gave them Squires and most importantly a Unique Tech in Castle Age that makes their Stables produce cavalry faster. However, the PowerCreep induced by ''The African Kingdoms'' civs makes them fall back to this again.
** In certain tournaments including 2017's ''Escape Game Masters 2'', Magyars weren't especially popular to pick either to ban or play. In spite of a mostly versatile late tech tree[[note]]For example, being one of the few civilizations to have access to Paladins and Parthian Tactics[[/note]], they lack eco bonuses early in the game[[note]]they were initially released with a free Hunting Dogs tech in the Dark Age before the bonus, then the tech altogether got patched out; now the only one close enough to an "eco bonus" is killing wolves in one hit, and that is more ideal for forward strategies than economics[[/note]], their siege is mediocre and their defenses lag behind. In ''[=EGM2=]'' alone, they were only picked twice in the whole tournament, both by the same player. Interestingly enough, they are considered one of the better ''Forgotten'' civs during release, as the others fare ''even worse'' before future expansions buffed them. This eventually led to a buff in patch 5.5 where Magyars were given several buffs where they become a more solid civilization while still keeping the MagikarpPower nature of the civilization.
** The Vietnamese are rarely played in tournaments, mainly because of the MagikarpPower nature of the civilization (having an incredibly bad early game since they don't have any strong eco bonuses across from revealing the enemy position at the start of the game, and even so, this is only useful for scouting your own base instead) and the fact that their civilization bonuses and unique tech, Paper Money, makes the civilization really team dependent. The Vietnamese were played in a [[https://www.youtube.com/watch?v=LRcWu9kFook 2v2 Return of the Kings tournament]] between a Chinese team and the Vietnamese team (ironically the Chinese team picked the Vietnamese while the Vietnamese team picked the Chinese), and the Chinese team lost. But this is because the Chinese team picked civilizations that are known to have incredibly weak early game (Magyars and Vietnamese) while the Vietnamese team picked civilizations that have a strong early game (The Mayans and the Chinese to a lesser degree).
