Why are you defending this so hard?
I agree that options are good but who can say just how much time and resources would be required for supporting both M/KB and gamepads? Would they have had to cut back on the M/KB optimizations (like the redesigned UI)? Would they have had to reduce testing for the M/KB controls and UI? I don't know the game's budget, dev cycle or resources so I can't really say. What I can say is that M/KB is the standard control scheme for PC and the optimal control scheme for shooters in general (I usually play them on the highest difficulty), so to me, gamepad support is unnecessary. If implementing gamepad support would diminish the M/KB support in any way, I'm glad they didn't do it.
It's been posted a million times in this thread that 2 and 3 man teams come out with gamepad-supporting PC games all the time. Why defend laziness?
Hell, we got game developers here on GAF. Let's ask them. Any devs out there, indie or otherwise, want to talk about whether or not it's actually hard to get controller support into a PC game?
