RE4 is fantastic, it really is. The biggest complaint I had were the Cave Trolls from Lord of the Rings.
Other than that, the game's an absolute blast. Has some scary parts and interesting, creative enemies, and is a damned fine Resident Evil game considering it's more action-oriented than it's predecessors.
I still play Mercenaries mode to this day. Lots of fun, that one.
Wanted to double-post so people saw this, but actually in a game of AvP2 Quarantine, on EU Server 1 if anyone wants to play. A few dudes in there!
