Was browsing through old forums and saw this and thought it would be interesting to give an update on Project M for anybody who isn't aware. The original PM dev team decided to stop for whatever reason and left the game in what most people felt was an unfinished mod. Another team decided it was in the communities best interest to finish it by adding the almost done character Knuckles and finishing balancing to the game. They changed the name from project Melee to project +. The mod is still getting updates to this day and you can find updates in their discord server, although they are done for the most part adding new content it mostly consists of balance and bug fixes.
