Well, you've come to the right place for this.
If you had 1200 Wii Points I would say Cave Story, but you don't, so I won't. Do you like Sega Genesis games? Because Shining Force 2 is on there and it's a very good strategy RPG. Aside from that, the usual: Donkey Kong Country 1 & 2 are fun (don't get 3, it sucks) and Super Mario World is, of course, a classic.
ooo, forgot about Donkey Kong Country. I think I'll get that one tonight. I played a bunch of Super Mario World on the demo machines in various stores when they were selling the SNES, but I always preferred DKC. thanks Eel!
