I just ordered a copy of Resident Evil 2 for the cube, a game I'm ashamed to say I've never played (have only played remake and 4). Can't wait.
One thing I love about the Wii is the GC backwards ability because its allowed me to play Resi 2 and Resi 3 again on the Wii via the GC remakes. I played Resident Evil 4 as well, which uses the Wii controls very very well and the remake of Resident Evil 1 (Archives) is a solid buy
. They also have the Zero remake in the Wii in the Archives franchise but I don't like Zero.
I'm playing through the series on my wii as well, so I'll get to Zero down the line.
