It'd probably be cheaper to buy a Gamecube and get the game. $99.99 for a new GameCube...RE4 is a Greatest Hits title now $19.95. I'm sure for the Wii you'd have to buy a Gamecube controller attachment and who knows how much that'll cost plus whatever it takes to actually get the game for the Wii. I don't know...It might be cheaper. I guess time will tell
