RE: Dungeons and Dragons, or something of the like.
What I don't mind about the dice is to see your character roll a 1 on something such as a diplomatic check. You then have to play your character messing up which can be very amusing for someone who made a potentially overpowered character.
So 1's are something to embrace, you sometimes come out of them anyway A-OK.
Anyway, as for being a DM, I ain't got experience in that but if you guys did a DnD thing I guess I'd be open to it depending on how it gets set up and the rules about dice rolls as it would be important that people be honest about those.
