Some games are repackages with updated information. There may be small improvements in one area or another, but most features are unchanged to a point where an answer to a 2005 game may be the same to a 2016 game.
FIFA, PES, FM, WWE, NHL, NBA and Remastered Games are pretty much all the same. WWE introduces new attires, changes the story mode, but the match rules are mostly the same. FM updates the rosters (and attributes), and from time to time redoes how contracts work, adds new animations, but some features are left unchanged for years. Final Fantasy VII got a remastered version, but the stories and game mechanics are pretty much the same.
Those titles can generate questions that are concerning one version, however they may also be present in some or all other versions of that game. I just posted this question. Testimonial matches are featured since at least FM09, meaning that the answer to my question may as well be the answer to the same question for FM 09, FM 10, FM 11, FM 12, FM 13, FM 14, FM 15 and FM 16.
That's a lot of Fs and Ms.
I was thinking that on these situations, and only on situations where the answer may be (and if proved otherwise the tag should be removed) applicable to previous titles (and future titles if the "future" game already exists) we could tag them differently. Similarly to minecraft.
Minecraft mods require the tag minecraft and the tag mods. Questions whose answer may be applicable to other games in the series could be tagged name-omni, or name-* (although the last one may be problematic as it brings automatically all tags eg: game-1, game-2)
If not for a tag that connects all answers, what should be done in cases where the same question, with the same answer, but for different games (and as such different tags) occurs?
