RE: 2

Resident Evil 2 remains one of my preferred games on last generation's PlayStation and had the title been remade as Capcom revamped RE1, it might have been a remarkable GameCube title. As it stands, though, RE2 hits Nintendo's next-generation console totally unchanged and -- five years old, just feels completely outdated. The end port is not a bad one. Purists hoping to get all of the "survival horror" titles on one console will probably satisfied, and if you've never played RE2 before it's still an enjoyable enough adventure.
It comes down to this: at $19.95, I'd recommend the game. But at $39.95, which sadly it retails for, I just don't think it's a good deal.

Wait for it to drop in price if you've absolutely must own it. Otherwise, get the PS1 version. Or better yet, wait for what is bound to be an outstanding sequel in Resident Evil 4.

RE:3
With the recently re-vamped Resident Evil and Resident Evil Zero titles drawing critical acclaim from everyone here at IGN, it's difficult -- no, impossible -- for either Matt or myself to recommend this game over either of them. Gamers who are expecting a similar experience with Resident Evil 3: Nemesis are going to be in for quite a letdown. The gameplay design is still as brilliant as it ever was on the PSX, but the overall package is not even close to earning its sticker price. However, if you've never owned a PSX and are feeling eerily nostalgic, then you could always consider it as an educational, historical, and enjoyable rental.
