The steam deck is kinda inconvenient when any level of tinkering is required due to switching between game and desktop mode and the input if you dont attach a keyboard and mouse. Non-deck distros lose the quick settings which I really like.
Try bottles too. you may or may not find it easier than lutris. I find the dependencies easier to install. After checking if anyone has already documented what dependencies are needed (directx, dotnet, etc.), I usually start with the default wine bottles uses, then try wine-ge and tkg at least before giving up. I have yet to find a game that cant be made to work but other software can be very finicky especially once dotnet is involved.
I still haven't had a better arena shooter experience than back in the xbox lan over the internet days
