First off, I must admit that I never had a chance to play the game, so this is only my own observations from reading the rules and some of the forcebooks. Now that I have that out of the way...
Personally, I was not very impressed with the rules. (braces for the expected pummeling) The minis are awesome, the background is some of the best that I have seen, but the rules seemed cumbersome. Using the whole action point (movement point?) system seems like a very slow system for any game involving a number of minis. Keep in mind before you try to rip me apart that this is just my opinion from looking at the game and reading the rules. That said, I have two basic boxed sets that I picked up cheap, a squad of Union power armor, three of the small Union drones (ADTs?), and the force books for Union, Neo Soviets, and Pharons.
