I definitely like the idea of enabling robots and allow them to move for 10 or 15 seconds before the drivers controls are enabled. That would make us think more about sensors and that kind of stuff and require some programming, that would be interesting...

Also, I like the ice idea, but I think it would be hard to make sure that the ice doesn't get to warm from robots giving off heat and moving on it. And water would be every robots dead.

Dirt, nope, harms a robot....

I like he rope idea: Let the robots move along a rope to reach anothe part of the playing field where they can also climb onto boxes of different height to score more points.

I like two robots going against two; four against four (i believe it was tried earlier didn't work as well); and there should be some teamwork, 2 against two this year was very good.
That's general things...

I'm working on a complete game and rules and will post it when it is ready.
