This. The Steam controller will be the best one, but it’s not everyone’s favorite, and one of the cool things about steamOS is you can use a controller you already have and love. I imagine there are plenty of people who would prefer saving money by buying one without a controller packaged in.

This might be good on Steam Deck for multiple games that have carry-over data. Just mirror the save data folder of one proton directory into that of the follow-up game’s directory. I assume you can go back to the first game to unlock more stuff to carry over, and not have to manually copy-paste the save folder each time. Just run a sync.
