&gt; I don't really play "cinematic" AAA games so I can't give a firsthand review of stuff like Sony/Ubisoft stuff

I've heard secondhand that external launchers and anti-cheats are the only things that really give the Deck trouble. No clue if uPlay still exists but if it does, i'd look into specifically how assassin's creed runs on the Deck. I don't have any games with those things other than Elden Ring's EAC implementation, so I have no idea how true those statements are, but the general consensus comes down to "unless the devs are actively trying to stop you from playing on Linux, you'll probably be fine".

It smells nice as well.
