There are three "fate" tags at the moment: fate, fate-core and fate-accelerated.
FAE emphasis makes sense, but distinguishing Fate Core from "just Fate" seems redundant:
If fate is supposed to be a "generic" Fate tag, then fate-core or fate-accelerated questions should always include it. Therefore, this tag gives no unique information about the question.
Many Fate variations are based on Fate Core. There are no "just Fate" rules, even the FAE is basically a hacked Fate Core.
There are many questions (including FAE-related) that randomly have or have not fate or fate-core tags (or both). The difference between fate and fate-core doesn't seem to be clear.
Shouldn't we merge fate with fate-core ?
