Let's not get bogged down in what is just a potential misunderstanding, and a tedious debate in any case: nomenclature.

But you want to get bogged down, apparently. There are many who disagree with your simplistic assumption. CRPGs are very commonly described as having specific elements, culminating in the isometric Baldur's Gate era. It's also common to just interpret the initialism simply, without reference to how it was actually used contemporaneously. You can ignore interpretations that disagree with you, but that doesn't mean they don't exist. Are you enjoying this tedious debate?

I said that MUDs owing their creation to multiplayer games was undeniably true. "Undeniable " doesn't mean that no one is able to form the words of a denial, it means that a neutral investigation of the facts has only one possible result.

And your claim that "The vast majority of computer games used to be singleplayer only due to technology" is immaterial to the evolution of MUDs. Are you pretending that because most consumer computers were not networked before 1995, MUDs, which appeared in the mid '70s at universities and technology firms, must have descended from such single-player games? That's ridiculous, a sophist's and liar's approach to debate.

From wikipedia's article on MUDs:

Colossal Cave Adventure, created in 1975 by Will Crowther on a DEC PDP-10 computer, was the first widely used adventure game. The game was significantly expanded in 1976 by Don Woods. Also called Adventure, it contained many D&D features and references, including a computer controlled dungeon master.

As I said, before MUD's there was no tradition of comuterized rpgs to draw on. They drew instead on multiplayer pen and paper games.

You made non-factual claims and are now just in the dance of "I won't admit I was wrong." It's ridiculous and tedious, as it always is.
