What about an automatically created game? The game is created every X minutes/hours, and only one game. Once it fills up, no booting, or anything, just gotta be one of the first to get in. This map would only be for end game, and every time a new campaign comes out, the map, loot, and boss are changed making some of the gear, very rare and discontinued (that or change the gear to the highest level and update the stats, IE, level 55 fury champion sword turns into a level 60 (place new campaign sword name here) champion sword) Would this be too complex?
