Right now these two tags have significant overlap, in that they both 100% equally apply to "I'm teaching a system to players for the first time" questions, with no distinction I can see between them to help choose the right tag.
- new-players: "Players new to a specific system or to RPGs in general."
- system-introduction: "Information, methods and tools for introducing GMs and players to a system and to help them pick it up."
Those are just the tag wiki excerpts (the popup when you hover over the tags in the tag chooser), but it illustrates the overlap nicely and the full tag wikis don't lessen the overlap.
Can we figure out how to separate these two tags into distinct usages, so we can unambiguously say that this question takes one and that question takes the other?
A working example:
I just retagged this question to have system-introduction instead of new-players, and only after noticed that new-players wasn't actually wrong according to its usage notes. It's a nice clean example question that should only take one tag or the other and I have no idea which.
