TheSaint54: I had one pre-ordered but cancelled before mine was shipped based on the reviews I read (i.e.- feels cheap, not a good substitute for K&M, takes a long time to get used to it, and customization can be tedious as one has to "generally" make a custom setup for each game).
I have still somewhat kept-up with the controller and am still waiting for a good way to customize games outside of Steam.
Perhaps Steam Controller 2 will allow it? That is if they have made enough fans of this one to even make a controller #2.
As far as I'm aware the software for it is still in beta mode so you never know. Anyway those reviews were the same reason I didn't buy one day one. I regret that decision lol. Playing the shit out of Bioshock with this thing. It feels soo good.
