It got bad reviews pretty universally, I think because of expectations. Coming off of mechwarrior and such, they wanted something action oriented. It's a very slow game with tons of menu customization and set up time. Those who know what to expect, i.e., those who were looking for the next FF Tactics or Dynasty Tactics, loved it.
I haven't played it yet, but my friends highly recommend it. Just know what you are getting. You aren't driving mechs around, you're picking options from a menu and playing a board game. A board game that kicks butt.
