Semen, (What the...)
Tl;Dr :
Use tags to describe "Game wallpapers" within the general category.
These are not the only filter.
You can:
1) Search by tags e.g: "games" or #games in the search bar.
2) Filter by purity.
3) Filter results to get a certain resolution/ratio.
4) Sort Wallpapers by Relevance/Date added/Views..etc
5) Search category.
Think of "People" and "Anime" as categories rather than just tags that describe wallpapers. Categories have limits. Tags, however, don't.
"People" groups every wallpaper that contains human beings.
"Anime" groups every wallpaper that contains any sort of Japanese style (ah... Japan™)
"General" groups every wallpaper that:
1)is not based on an anime film/tv show.
2) doesn't have a human being.(this includes the "gaming" tag)
I'd certainly vote against another ugly drop-down list. For what? I already have everything I need. A search bar and 5 awesome simple filters.
Simple. Clean. Efficient.
When you search for something on wallhaven, you are basically searching for wallpapers that fall under every tag that is relevant to your search term.
That being said...
"People"(Category) has tags.. e.g: model.
"Anime"(Category) has tags.. e.g: Vocaloid.
Wallpapers under these categories can share some if not most tags. e.g: Cleavage, Eyes and etc.. (Because, apparently, anime girls are girls!)
However, "Anime" wallpapers cannot be described using "real" tag and "People" wallpapers cannot be described using the "Hatsune Miku" tag (unless it is a name).
Of course, I excluded some points such as: paintings of people (other art) and tv shows (real house wives (hehehe) and etc...) headache.
(^How I view it/ Just my opinion!)
You'll have to search for what you want and decide under what category it falls, at least for the time being.
You'll end up either with an anime girl with a game controller or some mainstream game wallpaper/high resolution logo.

Check /wg/. They've got some decent high resolution wallpapers.
