Well, the official word from Jim is this:
James M Ward wrote:There is kind of an amusing story behind that. Yes it does refer to me. Back in the good old days when the AD&D game was being playtested I wasn't high enough level to actually have a Meteor Swarm but I could get them on scrolls. At the time I needed something more substantial than fire to do the job against my enemy. It wasn't clear what the spell did and I maintained (as long as it wasn't written down any where) that the spell generated a huge mass of flying rocks. Rob Kuntz as the referee disagreed with me, but had to give me my due because it wasn't written down yet. When those rules came out, suddenly my interpertation was 'legally' wrong, sigh and the once useful Meteor Swarm became less usefull. That's life in the rough and tumble world of AD&D and D&D. ;)
