True, but lord Gabe is aging, and I’m not sure what will happen once he’s gone. If Steam falls to greed, screwing up it’s user base and developer base as so many others before it, then I imagine a wave of pirates of significant proportions will emerge.

Of course!

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.
