I'd also like to add that RE2 was pretty scary back in the day. I was 12, I think, when it came out, and it was rated Mature. My mom was all like "it's rated M! It's too violent for you! It'll give you nightmares!" blah blah blah.. which was entirely possible, the "Thriller" video by Michael Jackson used to give me nightmares.
Anyways, RE2 is the only one i've ever really sat down and went all the way through. The only time I jumped was when a pair of hands broke through a window.
Parasite Eve's FMV's were pretty disturbing, namely the one in the park. I won't spoil it, but it's messed up.. RE2, PE and PE2 still remain, along with Snatcher and Harvest Moon 64 (complete, suckas!) as my favorite games ever.
