I buy Switch games and play them on my Switch (bought and playing Super Mario Wonder on it right now), but I also would like to play them on my Steam Deck as well (haven't gone through that process to get Switch games working yet, only older systems, but I will eventually).

For some games, it would be nice to only have to bring one portable system with me (like I own Advance Wars Reboot, but I think I'd prefer playing it on Steam Deck and being able to bring it with me along with the rest of my Steam library).

Same with older systems. I own tons of retro games, but I'd rather play them on Steam Deck (especially since it has integration with Retro Achievements) than dig out my old consoles.
