See, the thing about the older RE games is that they're not really very good unless you have nostalgia for them. Back in the day they were atmospheric and everything, but now...not so much. And they're kind of terrible to play.
Resident Evil 1 (not the GameCube remake) has amazing voice acting.
RE4 is fun. So is RE5.
That's what I have to say. There are plenty of people who will disagree with me, and say that the original games are great and everything, but really, you need the nostalgia to really enjoy them in this day and age.
