from what I’ve read on RISK 2210, is that the same combat rules apply as with the general play of the game compared to the original. The new differences include underwater territories and cities, nuclear tech., moon territories, and “commanders”. The commanders are basically acquring diff. tech. capabilities. There is a Nuclear Comm., Moon Comm., Naval Comm., Diplomatic Comm., and one more i forget…each comm. plays a different role. Overall, from what I’ve read without seeing any board or anything, I think I’ll be sneaky and convice my friend to buy it so we can experiment…muwahahaha!!!
