I haven't had a chance to read all the posts.(I am visiting relatives and have only 5 minutes left of my hour of leased Internet) But five bots bothers me. So Here are two devious possibilities.

1. There is a "house" or official bot, that has to be overcome - to be overcome it must be neutral, or able to be utilized fairly by the other robots in some manner. I like this better than:

2. Five robots are on the field, but the alliances are formed after play begins either as a strategy or by some random event. (I would think this is too devious even for Dave Lavery to come up with, but I've learned never to underestimate Dave's ability to be devious in game design!)

About the green - you can bet that the CU-cam will be back, and the best programmers will have the best chance of doing well. About Montana, Climbing or putting something high (scooping up lots of objects, and them placing them in raised goals either by climbing a ramp or some sort of transport mechanism will be there.

And as always, there will be something the rookies will be able to do, if they have a platform that can move.

Finally, remember folks, the trick to winning is to score more points than the other team.
