If there is a tag for a game (generally this applies to less popular/proeminent games), can I use that tag for the game's sequel (this applies at least to the tag "sanctum", because sanctum 2 does not have a tag itself)? I know that most games already have a tag, even if they are sequels to games with existing tags (elder scrolls, gta, etc), but I can imagine that we don't have a tag for each and every game out there. Is there supposed to be tags for each and every sequel, or do we just keep using the old one if there won't be too much appearing on the tag anyways?
In most cases, sequels get their own tag - if you can't make the tag on your own, ask for it in comments or as you did here. After all, a sequel is usually its own whole game and questions about one don't always apply in full to the other.
If the sequel isn't actually a separate game but is more of an expansion, then it may warrant sharing a tag, but I can't think of any example that we would do this for.
