The PC version of Monday Night Combat is now available for purchase. Having played a bit of the beta, I can say that it's definitely an interesting little shooter with a bit of strategy to boot. In the move from Xbox 360 to PC, the guys at Uber Entertainment have done a fair bit of tweaking and improving on their product during the beta as evidenced by this developer blog at Penny Arcade (thanks, MaestroMaus)
It all comes down to how each input mechanism affects your ability to turn. On a console, the angle in which a player can turn is a function of both time and displacement of the thumb stick. No matter how far players want to turn, they have to pay a time cost. Even at the highest controller sensitivity, there is a time cost to be paid. On a PC the angle of turn is a direct mapping of how far you move the mouse. The time cost is variable and the better players get that time cost to approach zero.
