Not sure if anyone is a Front Mission fan, but Front Mission Evolved is on sale for $5.20 on GamersGate before IGN discount.
The cheapest it's been on Steam is $7.50 from what I can see, and the game is Steamworks, so it seems like a solid deal.
The game gets some mixed reviews, especially since it's an action game (more like the Armored Core series), rather than a turn based strategy RPG like the rest of the Front Mission series. That said, the combat is supposed to be pretty solid, the graphics look pretty impressive, and the explosions are supposed to be gorgeous. The biggest complaints I've heard about it have been that the on-foot missions are boring, and that the voice acting is sub-par.
Just thought I'd bring it up since it's a game that rarely goes on a good sale. Amazon just had it for $9.99 a month or two ago. $5.20 is the best I've ever seen on it by far.
