Game Mechanic: Limit Number of Spawns

[TheGreatErenan]

It seems that most of us enjoy matches that last longer than just a few turns, but in general it's not really desirable to have matches go on for 200+ turns, specifically in turtling matches. I was wondering whether anyone had ever given any thought to game mechanics that might be introduced to help ensure games don't go on practically forever.

What if spawn points were allotted a certain number of spawns per game and once that is used up they shut down? Or limit the number of wits per spawn (i.e. you can spawn 28 runners total (28 * 1) but only 4 bombshells (4 * 7), etc.)? Seems to me this could actually add to the strategic elements of the game. You only get so many spawns, so make them count.

I just thought of this, so I'm not sure if I even think it would be a good idea myself. Thoughts?
