So is pretty much all of the cloud services the average user already subscribes to. People still use them though.

Once we have super fast reliable internet we’ll likely have the whole computer as a service. We’ll just have access terminals basically and a subscription with a login, except for the nerds who want their own physical machine.

Cyberpunk fits your three requirements, and you can play it as a non-shooter if you want. You can go melee if you like that, or play as a cyberdeck user who hacks the cyberware of your enemies instead of attacking them directly (can be really fun, or repetitive depending on what you like). I agree with @trankillity though, wait and see if there’s a bundle with the new big DLC this fall. It is also going to be a massive overhaul of the game and bring tons of improvements.

Subnautica plays pretty good on the Steamdeck and is not a shooter.

If you like older RPGs and Skyrim but haven’t played Oblivion, consider looking into how to install Oblivion on the steamdeck along with a major overhaul mod(s) for graphics and gameplay. Oblivion plays amazing on the steamdeck with the controller mod, and it barely uses battery. I can play hours more Oblivion than I can any modern game, and with a graphics overhaul it doesn’t look that bad. Plenty of modern games look worse and still use up the battery in hours less time.
