Yeah.

Differences between PbtAs tend to be either conceptually quite small or huge, so even within that category I would have no idea.

D&D is, I believe, perfectly compatible forward and backward, which has been a point of friction for the folks who want to see the game evolve into something different. By design it cannot. So I’d say those are all the same, with very small conceptual steps to get into Pathfinder or 13th Age.

All the WoD games are cross-compatible-ish, but they also have huge subsystems that get bolted on. Really don’t know about that one but I do think of “WoD” as one game.

I can’t help but read the question as “have you played anything other than D&D?” Which is probably unfair but that’s my take.
