My dream gm's:
Well my first warhammer gm, when we were still young and games felt new and cool. So, I want past version of him running games.
Then there is my current dm, I think is best ever, only he was so much better when he had more time for thinking game stuff, and not rl-work-related stuff. Yep, I want past back.
Oh, and I want past variation of my own passion for running games return for me too.
Of strangers I think Keith Baker would be cool. Mainly because I don't really like Eberron, but when I read his stuff on boards about it, I kinda start liking it.
I'd really like to know what kinda dm Monte Cook is, I really like his stuff. Rules stuff, at least. Though I like many elements of his story backgrounds, they are a bit too bland to me as a whole.
And then of course I'd like to find dm, that can put out as interesting stuff than some story hours here have. And one that is open-minded enough to accept my character concepts.
Then again, I kinda try to save strangers from me as a player. I am kinda demanding as a player.
