A minor point of terminology:

In yesterdays’ comments I noticed a couple of references to rollplaying – whether this is a rediscovered bit of jargon or a spelling mistake I’m not sure, but it was a term actually in use in the 1980s, mostly as a derogatory sneer at D&D.

D&D, and every other game, called itself a role-playing game, because the player is adopting a character role. Those gamers who became disillusioned with D&D adopted rollplaying, or rule-playing, to jibe at the process- and dice-oriented style of gameplay D&D was supposed to encourage. There was no equivalent sneer in the other direction – presumably the ‘rule-players’ didn’t care.
