Rochard, which first appeared on the PlayStation Network a few months back, has done well. It has done so well, in fact, that the developers, Recoil Games, are porting it to the PC. Starting November 15, the game will be up on Steam for $9.99.
Recoil did a good job with Rochard, and I am a little excited that it will be making its way to the PC. I am always curious to see how differently a game plays on a different platform, and I think the PC is a good fit for this title. If you were holding out on getting it for the PS3, and think you'd rather try it on the PC, I encourage you to do so. Go forth and solve physics puzzles in space.
