Long back i had played a map based game whereby people controlled nations. Each nation had maximum of 6 players where (lets say in TW terms) Duke can change their rankings. Now co playing is largely accepted. Why not take this concept of co playing to next level. Each username can have 3-4 players, which can be removed as well. The creator of username can have privileges. And make tribe limit of something like 20 or 40 to compensate for number of players. It would have following pros: 1.Not many inactive villages (villages will not go inactive if 1 player leaves) 2.Smaller and active worlds (therefore more action packed worlds) 3.Players can be added / removed to username.
