I'm just not a PC gamer. I'm much more comfortable on the couch in the den with the USB keyboard on a tv tray infront of me. I can't stand moving with the mouse and the keyboard and I wouldn't have it any other way than with a controller.
I'll tell you one thing though, the most gigantic problem with the controller scheme by far is the ghastly targetting system. You have to press right and left on the D-pad to cycle through targets. This normally wouldn't be a problem but since you can only move with the left analog stick, you can't target and move effectively at the same time (unless you have two left hands of course). I cannot believe how Squaresoft would just overlook a problem as horrible as this. Would it be so hard to cycle through targets with the R1 button and have L3 be the software keyboard?
