One simple question to think:
Q: What "Resident Evil 4" would you buy?
a) GameCube. The original, great graphics, good gameplay, no extra content, $20
b) PS2. Graphics "not-so-good", trashed gameplay, extra content, $20
c) PC. PS2 port, terrible gameplay (no mouse!), extra content, $50
d) Wii. GameCube port, great graphics, suberb gameplay, extra content, $30
e) None. I wouldn't buy a game that looks old. OMG GRAPHICZORZ!!!
To me is a no-brainer...
