I have not completed any game in deck but occasionally played quite a few game from time to time. According to me any 3rd person, platformer game works great. I would stay away from competitive game. Other than that you will really enjoy it. Use chiaki4deck and download proper controller profile and you are good to go

Guess it calls for a new decky screensaver plugin. Would be great to hv something like that…

I am also running on sd card, seems fine to me… ofcourse ssd would be faster but sd is playable as well…

I however am enjoying PS5 to the fullest. I played almost all the game and also all the exclusive till Last of Us 2 in PS4. After which I kinda stopped playing as busy with work. Last year I bought SD and have been playing games on it. It is good for a quick game session between work when taking breaks. I bought a PS5 3 months back and also subscribed to 2 years of Deluxe (premium without streaming) and have been enjoying PS5 Extra games on it since then. It has been totally worth it for me. I do remote session on SD and play old titles and AAA titles I enjoy on PS5. I don’t plan on buying any games on PS5 though as its vey expensive and 2 years is good time for Sony to include it in Extra. May be I will not renew it after 2025 but till then its good to have.

Steam Deck has definitely been helpful as I work on Mac and didn’t wanted to invest on dedicated PC for gaming. Its excellent for what it does. Just that we cannot expect it to play recent titles. I dont mind 30 fps (have been playing in 30 for my life in PS4) and SD small screen, its not bad but smooth gameplay is very essential.
