As much as I love brawl as a game and as a collection of Sakurai-ian skinner boxes, even I have to take my nostalgia goggles off sometimes and admit that its a deeply flawed competitive fighter. For most of my time playing it, this didn't really matter to me because I didn't play it competitively, but after playing melee and the slightly more balanced sequels, it became clear that these more blatant flaws at very high level play were still manifesting themselves in the more casual modes. Project+ (and its predecessor PM) is an incredible solution to that problem, combining all of the best mechanics of smash to create a much better foundation for enjoying the incredible brawl content. It's one of the best mods for any game I've seen and is the definitive way to experience smash for my money.
