*UPDATE*
Upon careful consideration, I have decided to try and implement a way of 3/2 scoring in TILE WARS at GenCon. All games must finish (or double loss ensues) will ALWAYS stay in TILE WARS.
BUT - I think the 3/2 scoring system is the perfect way to encourage games to finish in under 30 minutes.
SO - here's how it will be at GenCon:
Complete win in 30 minutes or less = 3 pt win
Complete win in 31-45 minutes = 2 pt win
Game not complete after 45 minutes = Double loss (0 points for both)
I will still watch carefully for slow play, and will hand out warnings if need be. But I think the positive reinforcement is better than the negative.
This really changes little, since most games finish in 30 minutes anyway - but this way it encourages it even more.
Also - don't forget:
