If you play Civ 3 on hotseat mode I think you can enable something like that.Civ being turn-based, incidentally, has the opposite effects, it means you can make decisions at your own pace instead of having to run around and do everything on a timer. Imagine if you had only 2 minutes to take every action during a turn in Civ, and if you failed to hit the end turn button by the two minute mark you would lose 5 military units and 100 gold.
