When playing a game being able to decide length of game you want to play 15min, 30mins, 1hour,no time limits etc (ingame options to extend if players agreed)
1. Players in shorter games wouldn't built up troops to the extent nobody is willing to attack as the frist to attack allways loose and this type of game is slow and boarin.
2. Ive not allway got 2 hours to play a game, if l have to leave an AI takes over (posted separate on why this should no be part of game)
3. Less likely other players leaves.
