We currently have age-of-rebellion, force-and-destiny, and edge-of-the-empire tags for Star Wars. These three games use very much the same system - they use the same quirky dice, the same skill and ability check system, the same advancement track system, etc. They also share the same exact subset of the Star Wars universe. And while I will acknowledge they are not identical systems, there is far more alike between them than there are differences. More to the point, examining the questions already tagged with one or more of the game tags, the vast majority of the questions apply to all games. A large proportion of them already carry the tags of multiple versions of the game.
I am not suggesting going out and editing all 32 current questions (for now), but I am asking is if I were to ask a question applicable to one or more of those games, should I create such an umbrella tag?
This was previously discussed, with the conclusion that we should discuss this further when the new games come out. Two years later, those games have come out. As noted here, we have a wh40k to cover the exact same situation that Fantasy Flight has put us in for that universe.
