This is a great game, but took me the longest to get into (2 years) before I really had the patience to sit down and learn its rules. I am an old gamer back from the days of Avalon Hill's Third Reich and stuff like that, and I have just lost the will to wade through complex rules and such.
But I find I really like games which are intuitive and have pop-up explanations. This would be especially helpful in this game if the Reinforcement screen had popup's over every unit type. Stuff like Signal units, transports, hospital units, raiders, etc... could really use a few tips on what special abilities they have and when they come into play.
