I had a whole different post lined up about there being no way to match multiple categories, but I just tried it and apparently that actually exists in a way! Yay!

However, it's still got issues:

First of all, if I go to the "Local Multiplayer & Party Games" category and want to Narrow by Tag, the options it gives me are too similar to the entire category including stuff like "Local Multiplayer", "Local Co-Op". I feel like there's too much overlap there. Going to the "Cooperative Games" category allows me to narrow it by "Co-Op", which feels extremely redundant and also bizarre that it actually even narrows anything down - aren't all the games in that category Coop?

Sometimes I'd like to be able to either match multiples or exclude the tags that I don't want, so my second gripe is that it's only possible to narrow by one tag at a time. For instance, I might want to browse all Local Multiplayer games that are NOT in Early Access, but fall under the Indie and RPG tags. There might not be a lot of games in this category, but it would make it a lot more likely for me to find exactly what I want in that case.

Maybe some form of Regex-type smart category would be a good addition
