I made a short video. 5 minutes of me playing csgo with the steam controller.

I don't know what to say yet. The controller itself is really different from controllers I've used over the years. So I guess that's a good thing. The touchpads have haptic feedback, I didn't know that, but it feels good. The ABXY buttons are really small and somehow hard to reach although I have big hands and long fingers. Playing rocket league I often pressed the wrong button.
Regarding CSGO: Imho spray control is not possible, keeping/putting the crosshair where you want it to be works really good on the other hand. AWPing seems manageable. Movement control is really bad. Hard stops or counter strafing is out of the questions. But it's fun. I definitely think casual shooters are easy to handle. Of course it will take time to get used to this new layout and the touchpads.
For me - although I've only spent a few minutes with the controller - this is the best controller input option by far. I can really see myself playing racing games, casual shooters and building sims with the steam controller. Valve did a really good job! I like it
Edit: Of course I'm not thinking a controller would be a viable option for CSGO lol. I just wanted to see how it works out (not that good as u can tell from the video)
