For the uninitiated, Prof. Mohammed abd Rahman Barker's Perfected Game Rules are as follows:
1) We both roll dice.
2) If you roll high, your view of reality prevails.
3) If I roll high, my view of reality prevails
4) If we're close, we negotiate.
I consider myself a member of the first camp - I would call Prof. Barker's Perfected Game Rules the platonic form of role playing games - but I'm not sure whether that puts me in the majority or not.
