I'm not sure if I can handle Full Silly, sadly. On the other hand, it is true that a dark and serious game would be pretty off for this system.

Gareth, it's your prerogative, but it's just 6 pages. It's a very simple, very flexible system.

Is anyone here familiar with the North World webcomic? I advise you to track it down if you are. Some half-serious adventure fantasy+modern life setting in that vein might be a plausible option. Then again, the only preferences I heard so far are "fantasy" from Gareth and "silly" from Bunnita - if anyone else cares to weigh in, it would be appreciated.

I'll get back to you on the subject of dice and game mechanics later, if you don't mind. But yes, I was thinking of leaving the rolls up to the players. http://www.wizards.com/dnd/dice/dice.htm can be used for rolls. I trust people enough not to lie about their results here.
