I actually don't recommend spore for the Wii, but for the computer, because it is better to have a stable hand when creating creatures.
I recommend.
LoZ:TP --if you like epic adventures that are epically great.
Mario -- if you like playing with gravity and platformers, and all around fun games.
Brawl -- if your a Nintendo fan with friends.
Mario cart -- if you like racing
Wii play -- if you need more Wii motes, this game is basically $10 and is a fun little game.
