Super smash bros brawl is probably the best game thats only on the wii.
The story mode is called the subspace emissary the most dissapointing thing about this is that there are no voices the good about this is that you can pick anyone you want before the level.
There are other good modes on this game like classic mode and challenge mode in classic mode you beat person after person for about 10 - 12 fights.challenge mode seems never ending everytime you do a set they give you more challenges to do.
The game offers you over 30 characters and loads of new stages and melee stages you can also create your own stages which is easy and deadly.you can also save replays and take pictures of events and fights that you do.
Overall i think this is a unreal game with lots of characters,stages and great multiplayer 9.5/10.
