Believe it or not, there's a setting to turn off stuff like Early Access, VR, etc. categories in the Store listings so you never have to see them.

The problem is: Valve's UX is so terrible that I accidentally came across that setting once, and I've never been able to find it again. But it does exist.

... and of course 3 seconds after posting I can't find it, I managed to find it. See if this URL works for you:

Apparently you can also filter-out certain tags, so I can shove RPGMaker in that field and never have my time wasted by those ass pieces of JRPG shit ever again. Nice.
