This might be the wrong board to ask this, but here goes. . .
There's been a good amount of discussion on the role of the GM in old school D&D but I'm curious if anyone here has thoughts on GM stance in the slightly later old school fantasy rpgs such as Runequest, Rolemaster, and C&S.
Specifically I'd like to hear your thoughts on:
What is the role of the GM in these games assuming we play the games as (mostly) written?
Are there distinctions between the role of the GM in these different games? What are they?
How does that role vary from D&D? Does it?
Is their GM stance vastly different than more recent games like The Riddle of Steel or (maybe) Burning Wheel?
How would you run these old school rules monsters?
(If you need me to specify a particular set of rules--I'm most interested in Chaosium's Runequest 1st and 2nd editions.)
