Steam Deck here:

• No Man's Sky. The new update is great, and the expedition is just moving. Hard to believe it's been 10 years since the game release. So much has happened since, and now I can enjoy the universe, in the palms of my hands. I've tried playing at the lower settings at 30 FPS for better battery life and less noise, and it's actually pretty decent and more relaxing that way.
• ARC Raiders. Again, 30 FPS. 40 FPS is definitely doable here, but I think the visual fidelity can degrade so far this way that it can be too difficult to roam the more open areas and properly respond to threats: you may simply not see them because of the lower resolution you'll have to run it at to keep that 40 FPS stable. And the new update is amazing, too.
• THE FINALS. I will probably wait until 2026-10-20 with this one, when Season 12 arrives. Used to play it with gyro, but the AI that Embark Studios has been using to look for cheating behavior signals has been issuing bans to such players. so I'd rather cut down on competitiveness and not risk an account suspension for months (if that).
• Allumeria. Great mix of Terraria and Minecraft, one I'd been waiting for for years. Can't stop building!
• Ballionaire. Like Balatro, but with pachinko machines and different boards that add their quirks. Really fun in its style, too!
• Pumpkin Jack. It is Spooktober after all! Started it last year, planning to beat it now if I don't get carried away by No Man's Sky and "ARC Raiders* and THE FINALS again (so probably not beating it this year either).
• DERELIKT demo. The game's supposed to be out this year, but I just want to experience them retro System Shock + Doom 3 vibes already, 'tis the season. I really enjoy the visual identity of Hypestrange games.
