The only games I haven't finished are some SNES games like F-Zero and this Hockey game(forgot the name) and some other games that someone lost for me. I try to make sure that I beat every game I get, or I just feel that it's a waste. On F-Zero, my SNES doesn't perform too well, so games just freeze or crash for some reason. Also, I got up to this track where you have to go off a ramp and fly past a huge gap, but no matter how fast I go, the gap is too big and I can't seem to get past it (the computer players get through it with no problem). Personally, I enjoyed Mario and Luigi: Partners In Time A LOT. Easily one of the best games I've ever played. I hope I get to beat F-Zero sooner or later.
