That's very likely. When it comes to different game systems out there, a lot of gamers develop loyalties early, and strongly. My gaming group has been longing to play something other than 5E Dungeons & Dragons, but they have made it crystal clear that they will not switch to a different system ever again...not even to a different edition of D&D that they're already familiar with.
So to play Star Wars, for example, our DM had to find a 5E/SRD based version. And fortunately for us,
it exists (and it's awesome.)
