Currently playing Armored Core 6 with a Steam Controller, and I love it. But… the right track pad leaves a lot to be desired.

The best aspect of the Steam Controller, without a doubt, is the modularity and shareability of it. The standard control scheme a game tries to assume, most of the time it stinks. But being able to browse through community-made control schemes and finding one that works for me is fantastic. The highest downloaded control scheme for AC6 got me 95% of the way there; I just had to change the bindings of the back pedals to suit me. Now it uses the track pad and the gyro in conjunction-- track pad for big sweeping movements and gyro for small adjustments-- and I love it.
