Well i did this with sonic so now its mario's turn so my faveorite mario game is...Super mario galaxy 2 it seemed alot like galaxy 1 but i didnt play that so yeah and it had yoshi and a galaxy made for nestolgia.(spelled that wrong and spin offs are okay)
hmmm... mario and sonic at the olympic winter games (preferbly wii) omg the improvement over the chineese games. this game was amazing with all the charectors it's awesome both versions had there advantages, the ds has an awesome story, better multiplayer special modes, and the wii has a great score better exclusive events, and an awesome backstage vip shop
My favorite Mario game is definitely Mario Kart. I use to play non stop with a bunch of friends and always ended up winning. My second choice would be Mario Party games for the same reasons...never ending fun!
Super Mario World. Hands down. I've literally played that game longer then I can remember, and I still play it at least a little bit every now and then, even if it's only for 20 minutes. It's just a childhood game I can't drop.
