I recently started playing Dyson sphere program on my PC again and I get that lovely feeling of being drawn into the game for hours. But since it's a very mouse-centric game, I don't want to play it on a steam deck. And because I sit at a desk all day for work, I'd rather lay down on the couch and use my deck instead.
Are there any games like DSP that work well with a controller? I find that if I use the trackpad too much, my right wrist starts to hurt.
I've played Factorio with the Steam controller some 3 years ago. It worked just fine, so I imagine the steam deck will too.
The controller support is likely targeted more towards playstation/Xbox controllers, or perhaps for a smoother experience if you dislike touch-as-mouse.
