So Neko, are you saying that 1st Edition AD&D stole from other games?
Yes...it stole from Chainmail.
But seriously, Dungeons and Dragons has the advantage of being the first published PNP RPG, and I noted that with:
"They haven't had an original thought since adding roleplaying to the miniatures rules...and the jury is still out on that one." The last part of that is to note the point about being the first published as opposed to simply the first. There are an absolute ton of wargamers who claim to have done similar things as far back as the 50's for their own edification, but never had anything go to print. Difficult point to prove or disprove, really, and not entirely on topic anyway.
Initially, D&D ripped off the fantasy literature of the day for a lot of its most basic conventions. Alignment, class structure, demihumans and an assortment of monsters all spring from an assortment of popular fiction and ancient myth. At first, there wasn't a lot of competition as far as RPGs went, but as time went on, D&D did begin to borrow from games around it, even as it was borrowed from in turn.
If you really think about it, it's kinda difficult to see where WotC could be ripping off Blizzard: WoW is kind of a D&D rip off at its core.
Oh...and while I'm on repeating myself, I said "Everything in D&D is either copied, derived or adapted from another source". That's apparently a bit complicated, so let me break it down.AL-QADIM
- Yeah...good example. Thanks. Ever hear of Sir Richard Burton? We'll stamp that one derived, which is probably noted somewhere in the work.The Mind Flayer
- Oh...look eveybody. It's a brain sucking alien inspired by a host of crappy old sci-fi movies and pulp adventure comics. Again, clearly derivative when taken in context from the flayers first appearance.Standard D&D Settings
- largely derivative of Tolkien, Lewis, Burroughs, Howard or Lovecraft. Ocasionally simply copied outright.
Mea culpa on the use of the absolute, however. Almost everything, I suppose I should have said. I have no clue where they got the flumph, really. ^_^
