What is this Combat Commander game you speak of? Sounds interesting. Maybe I'll try it out sometime?
I have HEARD that the rulebook is is overwhelming in appearance only, the system itself is actually very, very playable and makes a lot of sense. I have also heard a suggestion that reading and setting up and following the example of play BEFORE actually reading the rules will help put all the rules you read into perspective.
I have HEARD that's a good way to learn the rules.
Let me know if the game is any good! :P
