I have little hope of a new MechWarrior game being worthy, but that little hope is enough to have me anticipating more news of Piranha's game. I didn't play Revenge of the Fallen, but the secondhand stuff I've heard hasn't inspired me. In any case, at least it'll likely inspire me to reinstall past robot games.
A game like this reminds me of how precarious franchise transitions can feel. As much as I want to play a FreeSpace 3, the thought of someone screwing it up almost outweighs my desire. Fallout 3 was really a miracle of design in that respect.
