Anti-Climax Boss: Rodrigo Borgia. The fight has an interesting bit of both him and Ezio using a Piece of Eden, but the idea isn't taken advantage of and afterwards it just descends into mashing the melee button on him.
Awesome Music: While the entire soundtrack is considered one of the best of the entire franchise, Ezio's Family is so good that it became the most well-known track and got Call Backs in almost every game that followed.
Catharsis Factor: Those beggar women who constantly got in your way in the first AC? They're back in the form of wandering minstrels. Except this time, so long as you don't pull out your weapon, the guards don't mind if you start a fist fight. Or, if you're feeling nice, you can finally throw money to make them leave you alone; they're like pigeons.
Bonfire of the Vanities: Girolamo Savonarola, the Arc Villain of this DLC, was a lowly friar who, upon stealing the Apple of Eden, from Ezio Auditore decides to use it on Florence to rule it as its tyrant. Wanting to plunge the city into the Dark Ages, Savonarola commanded that all items pertaining to the Renaissance, such as art and books, be destroyed through bonfires. To maintain his control, he had nine people—out of the many he brainwashed—perform acts including constantly praising his rule; hoarding food, water, and hay from starving citizens; withholding medical care from ailing citizens; making sure nobody leaves the city; and killing many innocents who object to his rule—one of which being [[spoiler:Ezio's Love Interest, Cristina Vespucci. When Ezio manages to kill all nine lieutenants, weakening Savonarola's control on the city, the latter tries to increase the Apple's power onto the angry mobs surrounding them, possibly killing them. Although not a Templar like Ezio's other targets, Girolamo Savonarola was still a twistedControl Freak, obsessed with oppressing those he could, and destroying those he could not.
Practically every complaint with the original game was addressed in Assassin's Creed II. Too repetitive, not enough mission variety? Every assassination has a much more varied sequence of events leading up to it, instead of "gather information, stab mark in face." Uninteresting protagonist? Ezio is a lot more relatable than Altaïr. No tangible reward for collection sidequests? Now there are, and a full-blown inventory/resource management system to boot. Can't shake the beggars off? Ezio can toss money on the ground. Framing Story doesn't make sense? It still doesn't make much sense, but it's been expanded upon in a manner that shows that there are interesting answers to the many (many, many) questions brought up by the first game (as well as loads more Genius Bonuses for history buffs). Long cutscenes to establish evilness of victims? Save it for narration instead. Trippy, five-minute-long dialogues with dying victims? Shortened to less than a minute.
As seen on Metacritic, the first game got "Generally Favorable Reviews" (81), while the second game received "Universal Acclaim" (91).
Mercenaries are very good at distracting guards, but the game-breaking comes from the fact that attacking any enemy who is engaged with an opponent from behind is an instant kill if you're close enough. You can wipe out dozens of guards without breaking a sweat using mercenaries like this.
Smoke bombs, to a lesser degree. Pop one, and every guard in a surprisingly large area is helpless for about ten seconds, plenty of time to One-Hit Kill most or all of them.
Mercenarii and smoke bombs are the two main ways to get the "No-hitter" achievement (kill 10 enemies in a row without being hit while remaining in combat), albeit with mercenarii you have to hit at least one guard first to initiate combat.
If you're in a fight with guards you can't win or don't want to put the effort into winning, you can lob throwing knives at them. They're unblockable and only one (Florence/Tuscany/San Gimignano) or two (Romagna/Forli/Venice/Vatican) are needed to kill any guard in the game. If you feel the need to use them up-close, you can also pay a one-time fee for "special weapons" training to throw three at once, though the "charge up" animation before the actual throw can be interrupted.
Hidden Blades are this if your timing is consistently good enough; while its "window of opportunity" is smallest out of all weapons (unarmed is equal or a close second), they are the only weapon to always have a fatal CounterKill against any opponent not named Francesco de' Pazzi (at il Duomo) or Rodrigo Borgia/Alexander VI, irrespective of the opponent's Health. Other weapons only have CounterKills if the opponent's Health is low enough or if they're suddenly vulnerable (disoriented by smoke or sand, distracted by a NPC, just got disarmed, knocked down, bumped into, and so on).
Agiles, though they don't do well in a stand-up fight, can run you down if you try to flee, even when you're sprinting all-out. If you must run, your life will be made slightly better by at least slaying them first. Or, if you don't want to suddenly be surrounded by a dozen guards, you can just press jump when they get close to you. That'll confuse them for a few seconds and give you time to make a clean getaway.
This game marks a major increase in the substance of the series' storyline, and fully lives up to the potential in the first AC's gameplay.
A literal example: Ezio grows a Badass Beard in the Time Skip of recovering from a major stab wound between the DLC sequences.
Harsher in Hindsight: Everything to do with Lucy — including Desmond's ease of escape from Abstergo, and the fact Vidic finds the hideout so easily — come the revelation after Brotherhood that she's The Mole. Especially when she mentions the missing Assassin teams, which suddenly looks a hell of a lot more suspicious...
The page quote for Munchkin on This Very Wiki is: "Munchkin: One who, on being told that this is a game about politics and intrigue in 17th century Italy, asks to play a ninja." The latter part of that sentence has been potholed into the main page.
Subject 16's hysterical ramblings include a past life where he seduces a woman at the opera and talks about having sex with her. This becomes rather amusing when you know that his voice actor Cam Clarke is openly gay.
Ask half of the fanbase what they think of Leonardo and Ezio.
During the mission where you rescue Bartelomeo, he calls you "Madonna" and "bella mia" (my lady).
Iron Woobie: At the end of the game, you'll find Ezio to be one of these if you think about it a little. Ezio started as a young nobleman who was really just out to live life. His interactions with his family members showed that he had a loving relationship with each of them. Suddenly, his father and brothers are executed in front of his eyes forcing him to run and start a life of ceaseless bloodshed. Then when he finally defeats Rodrigo and has the opportunity to take revenge, he stops and says: "No. Killing you won't bring my family back." He proceeds into the Vault and Minerva essentially tells Ezio: "Your job is done, now shut up." And as of Brotherhood, his troubles seem to be far from over. Poor Ezio...
Jerkass Woobie: Many of Ezio's victims (much like Altaïr's victims) turn out to be simply misguided but well-intentioned people with their final words.
The PC version, at launch. Runs like molasses going up-hill in January (with crutches!), about as stable as nitroglycerin and has a DRM system so draconian that it makes all predecessors look good. These issues have been fixed, to an extent.
Subverted with the 2016 remastered version for PlayStation 4 and Xbox One. Polygon's comparison video documented incorrect NPC facial rendering that gave them horrifically bulging faces and eyes, and problems with the climbing system that caused Ezio to get stuck on walls. However, this video later showed that these glitches were in the original as well, and that Polygon apparently just focused on their presence in the remaster to tear it down and generate a faux-controversy.
Scrappy Mechanic: A small but very annoying quirk of trying to blend into moving crowds is that Ezio moves at a different speed from the NPCs; depending on how far forward you push the analog stick, he either moves faster than them or slower than them, forcing you to alternate your speed to stay on pace with them. Thankfully in Brotherhood, this was fixed so Ezio automatically matches their speed.
Shocking Swerve: Rodrigo Borgia becoming the Pope, for anybody who wasn't aware of that happening in Real Life. Prior to that, the game doesn't tell the player much about who he is besides him being the leader of the Templars.
Carlotta Moro's letter to the mentally-crippled Dante Moro, where she hopes that someday her former husband will be able to remember her and that she believes he still loves her, even with his mind destroyed. You only get to read this letter after you've killed Dante.
The title sequence is this for anyone who knows what happens to Ezio's family only a few days after that scene. The music that plays during this sequence seems designed to bring tears to the eyes.
"Port Authority", the Merchant assassination mission in the Bonfire of the Vanities DLC, is much harder than it would seem at first glance, especially considering that all the missions before (and after) it are exceedingly easy. You have to kill a guy who's tucked into a very secure spot on a small galleon, while ten guards with super senses patrol the deck and the surrounding pier. Oh, and did we mention you have to kill him without being detected? Unless you figure out how to make it easier note Shooting the shmuck that's walking on the docks will get most of the guards off the boat, letting you swim around to the other side, yank one guard off the boat via a ledge assassinate, double-spike two guards from behind, and then jump directly down onto the target; it requires good timing, but it's doable, this mission alone will make you regret ever getting the DLC.
The assassination mission "Town Crier". Sure, it's a pretty fun mission, but more than likely you'll end up getting shot down by an archer you forgot to kill. And even if you do kill all the archers before you reach the tallest tower, you may jinx yourself into falling hundreds of feet to your death, at which point you have to start the whole thing over.
Tough Act to Follow: Is still the most critically acclaimed and beloved entry in the franchise, thanks to its sprawling story, charismatic hero, large cast of Historical Domain Characters, jaw-dropping period architecture, and for making the most improvements and innovations on the formula.
