Aliasing underswap → undertale
Link to alias

Reason:

as well as underfell and fantasytale. that makes 3 alternate universe tags, were there any others i forgot about? i think there was...outertale? any others?

EDIT: The tag implication apocalypse_au -> undertale (forum #182933) has been rejected by @gattonero2001.

And undermafia.
Plus a whole lot of single-post tags. Reapertale, undereffect, errortale, undersail, underboss, underkeep...

Sigh.

They may be worth keeping so that anybody who wants the artwork of vanilla Undertale can blacklist the AUs, so I'd say imply instead.

I'd say imply. Underswap is a specific subset of Undertale art, and it would seem pointless to remove the ability to search for it (or blacklist it).

For comparison, we have a well accepted tag for pinkamena_(mlp) separate from pinkie_pie_(mlp). This seems like it fits in the same general category.

On further thought, it may be worth implementing an alternate_universe type tag. The easiest means for blacklist that way would be undertale alternate_universe and you can add in tolerable ones, like -outertale for those who like to see fancy space scenes.

Alternate_universe tag does seem appropriate for some of those.

But I don't think we need separate tags for crossovers such as Undereffect (Undertale/Mass Effect). Making new tags for every crossover would get spammy quickly, there's already far too many tags that are used exactly once.

For crossovers, there's already search functionality. Crossover + Undertale + [other thing]. So I think we can agree to throw all those out. I think, too, we can throw out all alternate universe tag names with only a couple pictures or all from a single artist. It's barely an alternate solar system at that point, and it's not helping anyone's search or blacklist ability.

Can't we just delete all those tags with only a few results? It's pointless to split it up to all sorts of "versions" of the game, might as well just use the umbrella Undertale for all of them.

Opted for implications instead of aliases for better searching and blacklisting.

Added numerous implications to Undertale, which can be found on its wiki page as well as to alternate_universe. The underworld tag was also changed to underworld_(undertale) to separate it from other franchises and outfitted with the same implications as the others.

I still added the implications even for rarely-used AU copyright tags in case more art for those are made in the future.
