I don't know about MK,.
Brawl is mainly a matter of time (esp. trophies/CD's).
However, The challenges are waaaaaay harder than anything in Melee. One example is Intense Boss Battle mode X_X. However, Characters and stages are easier to unlock in Brawl because of Subspace emissiarry and that they tell you how to unlock most of the stages via challenges...
PichuPichu, you've gotten all stickers and trophies? how do you tell?
