I think that last paragraph is important, if there isn’t already a thread on here about the definition of a role playing game I bet that would make an interesting and somewhat contentious topic.I actually disagree with this. I understand it, but I disagree.
I think that works as long as you're playing games that basically have the same structure and procedures. Where I ran into problems (and eventually "wrote" a "book") was when I encountered games that really didn't have the same fundamental flow.
So since then I've kinda come to the realization that roleplaying games are a much wider hobby than I had previously presumed, and now I prefer to approach each game with a bit more of a beginner's mind.
