Super fun racing game!!!
The graphics are beautiful (soooooo much better than 64) and the racing is smooth and comfortable. For mkds they took all the best levels from SNES, GBA, GC and N64 so you get the best of...um..4 worlds? yeah! its sweet. Online play is awesome and it gets so competitive you almost forget your a little lizard driving an egg! I wish there was online battle for this game but oh well, we'll get metroid for that i suppose.
The only complaint i have is that the racing itself seems a little slow, even when going 150cc you dont quite get that sense of rush and adrenaline like you did with F-Zero for GBA or something, but i think overall the gameplay and quality of the game makes up perfectly for little things like that.
