This has been suggested multiple times by multiple users already, but nothing has been done, so I'm just going to bring this up again in the hopes that someone actually listens and does something this time. Why is there no built in ability to filter out tags? Oftentimes, the top rated/most popular game lists for any particular set of search terms are clogged up by visual novels, or horror games, or gay furry games (no offense to LGBTQA people or to furries, but I am not one and thus have no interest in that stuff, and I know I'm not alone in that), or some other tag that dominates the top of the list. I know, these games are all highly rated for a good reason, I've enjoyed several horror games and visual novels myself... but rarely; oftentimes I'm just not in the mood. I am not going to check out these games regardless, so having those on the list for me benefits no one. And searching exclusively for some specific other tag (such as platformers, rpgs, etc) would filter out too many other things that I would be interested in playing.
And before anyone else points it out: Yes, I am already aware of adding in things like ?exclude=tg.visual-novel to the end of the URL. There are three problems with this. 1: It doesn't even work consistently; depending on the rest of the URL, more often than not, adding that has no effect. There are still just as many visual novels (or whatever other tag) as before, in all the same places. 2: Since the system is not built to accomodate the presence of this extra text, refining your search with anything else causes that part to disappear, so you would have to add it in again (not that it would even matter, since it works so inconsistently anyway). 3: We shouldn't have to use this weird obscure workaround in the first place. This should be just, an actual built in part of the site, that is easy to use and actually works correctly.
