July 2022 update: Since the tags have now been synonymized by community voting, this post now serves as a tag merge request to the mods. (Only moderators can perform a merge.) This is because many questions that have the skyrim-special-edition and skyrim-anniversary-edition tags still don't have the the-elder-scrolls-v-skyrim tag. Only merging will allow this to be done en-masse.
The original synonymize and merge request is as follows:
Currently, we have three (!) separate tags for The Elder Scrolls V: Skyrim, one for the original edition (the-elder-scrolls-v-skyrim), one for the Special Edition (skyrim-special-edition) and one for the Anniversary Edition (skyrim-anniversary-edition). I was initially planning on making this a discussion post to ask how should we tag the different editions, but have found out that this has already been discussed back in 2016: 'Skyrim Special Edition' question handling.
The community consensus in that meta post is to use one tag for all game editions. In line with that, I am requesting that skyrim-special-edition and skyrim-anniversary-edition be merged and synonymized to the-elder-scrolls-v-skyrim.
I've looked at all the questions currently tagged skyrim-special-edition and skyrim-anniversary-edition. The questions either already mention that they are about their specific editions, or are about an issue that is also in the original edition*. It should now be fine to merge the tags (as no edition information will be lost).
From the tag info article:
Users with more than 2500 reputation and a total answer score of 5 or more on the tag, can suggest tag synonyms. Users with a total answer score (total upvotes minus total downvotes) of 5 or more on the tag, can vote for tag synonyms. Suggestions will be automatically approved when they reach a score of 4 [...].
I've already suggested tag synonyms for the tags I've mentioned above. If you meet the requirements to vote for tag synonyms to the-elder-scrolls-v-skyrim, please do so at: https://gaming.stackexchange.com/tags/the-elder-scrolls-v-skyrim/synonyms.
Note that only moderators can perform a merge. Non-moderators can only do tag synonym suggestions and voting.
