When setting up pitboss for another game I furrowed my brow at the automatic turn processing. Essentially after a set amount of time the game would move the game along.
This really changes the rythmn of pitboss games as the game moves at its own pace, a weekend away means missed turns.
Colonisation seems particularly suitable due to the complete competence of the AI at housekeeping.
I would intend 48 hour processes and 4 players.
