I can't enjoy this game yet because I'm unable to get a single controller to work to a degree that the game is playable. Yes, I'm changing the controls in the game as appropriate.
Steam Controller - touch pads work, but none of the buttons, triggers or analogue stick when a gamepad profile is applied.
XB360 Controller - Initially nothing worked, but reading posts about Unity's shitty input manager lead me to remove SteamVR(!) and now I have working analogue sticks and face buttons, but no triggers.
I'm going to create a KB+M config for the Steam Controller, because those input devices seem to be working, but man, what a weird thing to mess up. I have zero controller problems in the other 100+ games in my library. I don't use any joypad/stick mapping software at all or other peripherals.
Fake edit: Seems like they've updated their information in the steam forums to say the Steam Controller is currently unsupported on Windows 8 and 8.1, which could account for some of the issues I see.
