That is disappointing to hear. I was actually planning to buy the Steam Deck to play 2010-2016 era action RPGs.
Someone said something about it before that makes sense to me - it's a portable PS4. If you are happy with playing games at the level a PS4 would play them, then it's a perfect device for you. If you expect proper next-gen games to run on it(Returnal) then you will be disappointed.
