Make it easy to play "one more turn". Each turn only needing a few minutes is what causes players of turn-based games to suddenly find themselves still playing at 7am. The built-in "pause" in the game's action—with each turn accomplishing a discrete task—offers an automatic offramp out of the game, which makes it easy for players to decide that they will take that offramp after "one more turn". If gameplay were not so discrete, players would at some point just pause the game on their own and leave.
