History YMMV / X

* UncannyValley: The Argon race portraits frequently dip down into the valley, and the Terran portraits to a lesser extent
* UnfortunateImplications: These ''really'' start to crop up if you start to think about who each race represents. Boron are squid, Paranid vultures, Split are warlike humans, Teladi lizards, and Kha'ak are insects/birds. Heck, there's even an unseen, non-space-capable Whale race that's protected by the Boron.

* CrowningMomentOfAwesome: ''{{X}}'' being what it is, the player generally makes his own CMOAs, so let's limit this to plot-related ones.

* DemonicSpiders: Xenon "M" interceptors. While they're poorly shielded, they come in huge swarms, and 90% of them will mount Pulsed Beam Emitters - weapons which are ''impossible'' to dodge. A single M can strip down the shields of an M3 fighter very quickly on its own - add in several dozen friends and you basically need a capital ship to kill them all without dying instantly in a hailstorm of (nearly) hitscan weapons.

** When ''Terran Conflict'' first came out, missions had ''very'' high payouts. A "Very Hard" patrol mission would net you about 20 million (enough for a TL or a fully decked out corvette). Said patrol missions could be stacked, leading to payouts of several hundred million, for about an hour's work - several thousands time faster than any other method of money making, save possibly for Nividium mining.
** Nividium mining in ''Terran Conflict'' and previous games. Nividium is an extremely valuable, rare mineral that can only be mined by breaking up asteroids and picking up the debris in ships. Normally, doing this will result in the Nividium being depleted. However, ordering your ships to pick up the debris when you are not in the same sector results in the game basically "faking" your ships picking up the debris - they'll fly around in the debris fields, and the game will cheat in nividium into their cargo bay, in order to save processing power. The game does ''not'' get rid of the Nividium that the ship is pretending to pick up, meaning that doing this results in effectively infinite Nividium. Mine the debris for an hour, load it all into one ship, sell it for 30 to 50 million credits at a shipyard, rinse and repeat till you have billions of credits. The exploit was fixed in ''Albion Prelude''

** Well, those and Flak Artillery Arrays or Starburst Shockwave Cannons.

** Briefly, a photo of an Egosoft exec at his computer (posted during the announcement of ''X: Rebirth''). The image on the screen started getting Photoshopped into all sorts of things, including an image of the egosoft exec at his computer.

** There's an achievement for completing all nine plots in Dead-Is-Dead mode. Problem with this is that, as mentioned on the main page, [=DiD=] doesn't distinguish between dying because your ship got shot up and dying because the RandomNumberGod decided to [[TeleFrag drop an M2 on your head]]. Or because the [[ArtificialStupidity auto-pillock]] crashed you into an asteroid.

* TheyChangedItNowItSucks: The reaction of some of the fan base to the fact that ''X: Rebirth'' will restrict the player to personally flying one roughly M6-size ship (as opposed to any manned, non-Kha'ak vessel in the universe for every other game except [=X:BtF=]).
** The ''Albion's'' {{Attack Drone}}s have [[IncrediblyLamePun taken flak]] as well: though you can take control of them remotely, if the drone gets blown up you return to controlling the ''Albion'' instead of dying. This takes some of the danger out of being a fighter jock, for those who enjoy it.
** Another thing much of the fan base is up in arms over is that ''X: Rebirth'' will be sold exclusively through {{Steam}}, whereas the other entries have been available without it.

* {{Narm}}: Many of the enemy pilot death cries but in particular a random Teladi comment about his ship being shot apart and his imminent horrific death - 'Lost profitsssssss!'
** Most of the other death cries fit this quite well. 'SPLIT CURSE YOU Awreughrguhrgh'. Or in the case of another Teladi 'Gruuuuurrrrrrrrrrrrrrrrrrrrrrrrghhhhh'

* GameBreaker:

** The aforementioned Hyperion M7 in ''Reunion''. While it's by no means a God Ship, and easy to kill when piloted by the AI, it becomes a one-size-fits-all pocket destroyer when flown by the player. Its superior weaponry lets it kill any other ship of its size, and its speed makes it fairly easy to dodge fire from ships several times its size - all the while pumping laser blasts in their hull. Bigger ships are still useful for massive fleet actions, but in solo play once you get that it becomes redundant to get anything else at all.

** SETA on 10x causes the game to optimize where it uses system resources; in other words, it will run AI routines slower (making them ''more'' idiotic), meaning that if the player hides in say a station while SETA is on 10x, in a combat mission, ''all'' enemy ships will plow into the station and destroy themselves.

** The Springblossom corvette in ''X3: Terran Conflict''. It's a corvette which has the firepower of a Prototype M6, can outrun most fighter craft, and has the cargo bay of a small transporter. The only disadvantage to it is its extreme (for a M6) price, the rarity of the weapons it uses, and the fact that the insane speed will mean you're probably going to end up ramming into enemies and dying, a lot. Its little brother, the Spitfyre interceptor, can outrun most scout ships, has the firepower of a prototype M3, and the shielding of a M3 Raider.

** M7Ms can wipe out an entire sector from a remote corner using a full cargo bay of missiles; the sheer volume of rockets will completely overwhelm any target who isn't using Plasma burst generators or Phased shockwave generators. Thankfully, the AI never uses M7Ms for this in vanilla X3TC.

** The Teladi's obsession with the word "profits" means they say it ''at least'' 2-3 times when you talk to one of them. With a very pronounced emphasssisssss on the letter ssssss.
