Just for kicks, I got HotD3 and the MadCatz light gun today. It actually seems to work fairly well. The only major problem is that it won't "reach" the corners of my TV as well as I would like. So while it doesn't have an ideal 1:1 range, I can calibrate it by pointing to the corner as far as it can "read" and then manually adjust while playing. It's not as bad as it sounds. So now I guess I have to decide in the next 24 hours or so whether or not I want to keep the gun just for this one game. I'd be totally sold if I knew there was at least one more decent game ... or another one coming in the future.
