[YouTube] Jon Peterson Interview: Gary Gygax vs Dave Arneson

[finarvyn]

Peterson talks about some of Dave Arneson's ideas as "one-offs". I am not sure what he means by that, but I could see it as things like the City of the Gods adventure and even Temple of the Frog, especially at a time when TSR didn't think adventures would be profitable (before companies like the Judges Guild and Wee Warriors proved them wrong). 

I think it's just the way it sounds. A "one-off" would probably be a product designed to be used once only, so a single scenario or adventure (probably a short module) which would be used and then moved on from. Compared to a campaign setting, I mean, where a sequence of adventures would all link together.

I think that the Braunstein concept was originally supposed to be a one-off and then players asked for a sequel. (Town in peril, banana republic, and so on. A bunch of individual games, unlike Blackmoor which was a campaign.)

At least, that's how I read it.
