Project M is a mod for Brawl that re-does the game to act more like SSB Melee. It puts back in Melee characters and also re-writes the physics engine to act like that of Melee. It also changes some of the graphics and music, and it also adds some stages too the game. It's meant for people who liked the physics of Melee and the competitive style, and I personally like it for that too. It's also good in the way that you have to open it through the homebrew channel, so if you'd prefer to play regular Brawl with friends, you won't have to deal with much fuss.
