you don't really need the classic controller unless you don't have a reg gamecube controller. Try putting this thread in the VC council area, not that i should be talking since i posted threads in the wrong area twice today
ANYWAYS i'd get metroid, tecmo bowl is good with two people, pretty much any of the nes or super nes games. the N64 games take up a lot of space i hear, plus if you have an N64, you could just get those games for that system if you don't have them already, much, much cheaper!(usually)
