Actually there is one rule change that I've been thinking about for a while now. See the picture below, think it's pretty self explanatory. If you've played 1,000 games on Tron and made it to Portal twice I'm sure you understand where I'm coming from. Tron is one friggin' tough game (but it's awesome)!
I think Centerflank has that Tron crybaby subforum around here somewhere, maybe I'll see if I can find where it is and sign myself up
