Trivia: Originally this game was going to be completely different, it even got though around 70-80% completion before being scrapped. Robert Kendo and Marvin (the gun shop owner and dying cop, respectively) were going to be Claire and Leon's partner characters, but when the game was scrapped as it played too much like the first game, they were given substantially smaller roles, both lasting barely more than five minutes each.
Trivia: During an A game, if the player gets to the police station without picking up any items, then they can fight a zombie Brad Vickers in the courtyard. Beating him will give the player the key to the locker in the police darkroom. The locker has new costumes for both characters, and a new gun for Claire.
Answer: I would say, not quite. As far as I know, the European and American versions would share mutual agreements and censorship with the content in the game. For instance, in the original RE4, if you kill an enemy by a headshot with the rifle in either the European or American version, it would show the headless enemy. In the Japanese version, you can still kill enemies by rifle shots and the enemy still has their head attached. It's just that in the Japanese version, decapitation in games is banned. If anyone can disprove me of regional changes of RE2, they're free to do so.
