Plagiarization in the creative industries (from impressionists copying old world masters, to writers, to cinema and of course, games!) has been going on…well, forever. In a way, it’s the only way we really advance as a species.
Now specifically with RM, let’s face it, RM would not exist without D&D. It was created as an improvement to D&D. Not a copy, new intellectual property for sure, but one that relied on D&D much like zynga relies on facebook. Until it became its own stand-alone game with all of the attendant support product.
Then look no further when the great Monty Cook who grew into his own at ICE, went to work on D&D 3.0 era. A number of changes were drawn from ICE (skill system which became a front and centre emphasis similar to ICE a big one). It’s annoying, but legally, not much we can do about it. In a way, it’s a form of flattery and proof that WE have the better system.
So it does not surprise me to hear they may do it again.
What I would say is that when you see these suggestions being made, that’s you chance to chime in and recite this history and say “Rolemaster has all that, you should check it outâ€.
