Thing is, the AUR isn't really meant to be your primary repo. You can really get anything into the AUR.
The reason why I love it so much is because if I need a package that's not in the main arch repo (which tbh isn't many), then I don't need to bother going to some github page and compiling from source, I can just find it in the AUR and it's all done for me. I did this with things like goverlay and it's one thing that I immediately miss when I distro hop away from something arch-based.
I feel like all the games I've sunken more then 50 hours into have some merit tbh. I've never really been into those super grinding or janky games that seem to be the target of the comments haha.
