Yeah, sold it.

Anything Sports related, Souls-like, MMO RPGs and Multiplayer FPS (except for Ground Branch) are a no no for me.

Some open world that I’ve played on the steam deck that run well with or without slight tweaks:

1. RDR2
2. Witcher 3
3. Spiderman
4. Cyberpunk 2077
5. GTV 4 & 5 (+ trilogy)
6. Arkham City & Knight
7. Hitman : World of Assasination (not really open world but still plays well with huge environments to explore.)
8. TES Series (mainly Skyrim, I haven’t tried the rest but haven’t seen them run well)
9. Mad Max
10. Metro Exodus (and series but they’re not exactly open world)
11. Project Zomboid
12. Days Gone
13. Fallout 4
14. Zelda : BOTW
15. Super Mario : Odyssey

And the list goes on, but I enjoyed the switch titles along with GTA, RDR2, Hitman & Spiderman the most.
