I was always tempted to get into the original ground game. I've only heard good things about it and I really like the look of some of the factions. Just never got around to it.
I'm a sucker for space ship games though, so as soon as I saw this I knew I was hooked!
I really like the ship designs, and the way each sprue can be used to build one of several different versions of each ship class. What I've heard of the rules so far sounds good, and I like the unique "orbital" element of the game. Finances are a bit tight with the holdiays and all, but I still managed to find the money for a pledge.
