I know there's always threads about help with finding a game but I really need help. I can only get one and I need it to last for a couple months. Here's a list of what I'm considering since I only have $50.
RE4(never played it but looks fun)
Sonic(I like Sonic but the gameplay looks repetitive)
Paper Mario(It's Paper Mario!)
CoD3(I liked big red 1 on PS2)
or a $20 GC game and 2 controllers(preferably CoN2 but I have no memory card)
