It is a pretty straightforward game. Alternating turns, somewhat limited command and control, which is determined by tHe number and quality of commanders present.
The British vs Red Martian rules play pretty much like a British vs Zulu game, with a little air support. In long games the plus and minus modifiers can get a little numbing, but it really is a good game overall. We played two of the book scenarios, and had a great time. You do have to make some choices as to which units will get activated in a turn, and which ones will not.
