Recently finished Bioshock, Spec-Ops: The Line and Nier Automata (not so old, but played really well).
I’d love any suggestions for older AAA titles that are worth a play-through!
You can never go wrong with Dark Souls.

I started the Batman Arkham series and it’s super fun, holds up just fine! Regularly goes on sale for super cheap. I got the whole trilogy for 10€.
Are they playing well on the Deck? I see a lot of protondb posts say that the games have a ton of crashes. Which is why I have avoided trying them out.
“Assassin’s Creed: Odyssey” plays incredibly well on SteamDeck, looks gorgeous and has (almost) none of the annoyances of other AC titles. It’s considered the best AC by many. I use it as a Skyrim replacement because I couldn’t be bothered to port & maintaine 1.300 mods + Vortex on the SteamDeck.
The “Crysis” Remastered series also plays very well and is a fantastic shooter if you’re into FPS.
