I liked the scariness and the tension that Nemesis had in RE3, as it was awesome, but RE2 is still the best in my book. I guess the thing is, in RE3, you are gradually introduced into the action as opposed to RE2's *CRASH* "OH SNAP ZOMBIES ARE EVERYWHERE RUN!"
Plus you had to play RE2 8 (senarios A & B) times to go through each story line on every difficulty
(awesome replay value)
plus the Item randomizer
PLUS it had hunk....and tofu x3
