Tags with poor man's tag warnings (screaming in the tag wiki excerpt):
legal
Questions asking if something is (il)legal are off topic here.
xbox
This tag is exclusively for questions about the original Xbox, released in 2001. It should not be used for Xbox 360, Xbox One, Xbox Series X/S, or the 'Xbox Games' feature of Windows 10.
dota
USE THIS TAG FOR QUESTIONS ABOUT DOTA 1 (THE WARCRAFT 3 MAP)
cheats
We do not allow questions about multiplayer game hacks/exploits that ruin another player's experience for personal gain.
system-requirements
This tag is for generalised questions about system requirements not specific to a single PC or laptop.
google-maps-pokemon
DO NOT USE FOR POKEMON GO
hardware-identification
These questions are allowed only if you have an actual screenshot, video, etc. of the game hardware you want to identify; not just a description of vague recollections.
(I've excluded things that already have answers above, as well as completion-time which I wasn't sure what to do with)
Not necessarily saying all of these warrant tag warnings, and they should probably be rephrased if they do warrant them, but something to think about. This is a community wiki post, so feel free to edit in any better wording suggestions.
