History YMMV / SonicAdventure2

* AluminumChristmasTrees: The idea that the media would mistake Sonic for Shadow at first glance isn't that much of a stretch:
** Eyewitness testimony is notoriously unreliable in RealLife, to the point that people mistaking Shadow for Sonic isn't as big of a stretch as it may seem.[[labelnote:To elaborate...]]People tend to subconsciously alter their memories to conform to their expectations and/or biases (e.g. someone raised to believe that [[ScaryBlackMan black people are criminals]] or [[FemalesAreMoreInnocent women don't commit crimes]] may recall a crime being committed by a black man, even if the perpetrator was a white woman or dressed in such a way that their clothes would conceal their race and gender).[[/labelnote]]
** This comes even before considering that Shadow is a fast-moving hedgehog handling a Chaos Emerald, when Sonic is the only one in his world that could fit such a description until Shadow showed up, or that Shadow was mostly seen at night on Radical Highway, a setting in which his black and red coloration gives him a certain amount of camouflage.
* AngstWhatAngst: Near the end of both the Dark and Hero stories, Dr. Eggman has Amy, a 12 year old girl, at ''gunpoint'' and threatens to ''shoot her in the head'' if Sonic doesn't hand over the final chaos emerald. Despite the seriousness of the situation, when Sonic does arrive, he simply smiles and cracks a joke about Eggman "turning into a big time villain" before confidentially walking into the room. Granted, it's ''possible'' Eggman wasn't actually being serious about harming Amy and Sonic just knows him that well to tell, but he still acts weirdly unfazed to the fact that his friend's life is being threatened right in front of him.

** The second Tails vs. Eggman battle. The level has no rings, meaning no regaining health, and your enemy will pull out special attacks that do massive damage are extremely hard to dodge with the slow character you use. The version when fighting as Eggman becomes a BreatherBoss if you got the Protective Armor upgrade in Cosmic Wall, but doing so as Tails is ''harder'' since Eggman has the effects of the Protective Armor upgrade and thus take even less damage where as Tails as a boss just uses the missile upgrade which won't have any real noticeable advantages against you.

* AssPull: Near the end of the Hero and Dark stories, Eggman manages to trap Sonic in a chamber and has him shot out of an airlock to plummet to Earth to his death. How does he get out of this? He performs Chaos Control with a ''fake'' Chaos Emerald. The fake emerald was made by Tails to mimic a real emerald's power signature, but it doesn't actually have the same output of power. Not only that, but Sonic only recently discovered what Chaos Control even is when he saw Shadow perform it, and the latter only performed it ''once'' in front of him. Yet, Sonic is somehow able to pull it off on his first attempt with no experience or knowledge on how to do it.

* HeReallyCanAct: While the voice acting in general is hit-and-miss at best, Marc Giagi's performance as Professor Gerald perfectly captures his grief, rage, and insanity.

** With the announcement of the third ''Sonic'' movie that will be an adaptation of ''Sonic Adventure 2'', many fans have joked that it will depict the scene where Maria was gunned down by G.U.N. officers -- except the game didn't have this scene. While it's all but stated that this was her fate, it's never actually depicted on screen or said outright. The scene itself was actually depicted in ''VideoGame/ShadowTheHedgehog''.

* SacredCow: While not without its issues, ''Sonic Adventure 2'' is still considered to be a fun and influential 3D entry, thanks to its improved controls, more streamlined progression, compelling story, and the plethora of memorable levels and set pieces. The fact that Shadow and Rouge were introduced in this game doesn't hurt, either.
