The multiplayer is by far the best part of Halo 3, Halo 4 has got a lot to live up to, especially since reach sucked. H3 could easily be repopulated if maybe? The Bungie favorites were updated once in a while, the ranked double exp weekends still existed, team objective, squad and 1v1 playlists were brought back and stats were still available. H3 wont die, but it does need a little bit of attention, which it's owed imo.
