As the OP of the referenced question (and also the respondent to that question), I thought I should chime in.
I asked this question to help someone else figure out a conversion from D&D 5e to Dungeon World. It seemed like a reasonable question that I could answer and keep for other readers, so I posted it as a question on the site.
I did consider other PBTA games. The consideration went like this: "Gee, there are a few other games like this one. I'm totally unfamiliar with those; I should probably just stick to what I know." From that irrefutable logic, I chose to limit it to Dungeon World.
I agree pretty strongly with the conclusions of Wibbs and doppelgreener in their respective answers. Here's my logic:
If any other systems match closely enough that these stats are useful, then great!
If they don't quite match, then I'd say the other system deserves a Q&A like this one. I'd even be happy to reply to that as well, if someone points me toward the rules for that system. However, expanding the current answer to cover rules from other systems would just dilute the content for the original target.
