I think one of the most important aspects of roleplaying is the character creation process. I probably think that because of the experience Ive had playing for many years with my good friend and your author, Mister Wright. We have always had me and him, but who wants to play a RPG with one other person? That elusive third person would show up from time to time and we would game.
But by the next time we met #3 again, we managed to either lose the character sheets or forget what we were doing anyway. So we would reroll, and reroll again the next time. Which isn't a bad thing unless you have some sort of byzantine rule system to try out, or have to write down all those silly powers (I'm lookin at you 4e).
