I've been interested in spartans entire line of games since I first heard about Firestorm: Armada. Having played BFG, I thought that FSA would probably hold my interest a little more because it wasn't as "we're doing 40k only in space."
Since I picked up the rule book this past weekend, it appears to have a lot in common with what i remember from the FSA rules, and adds too them. I can't wait to give this game a shot this weekend.
The only complaint i can see with the game is that there are no scenarios but as with all of their other games, the community will step up and release some on their forums.
