Someone is always the butt of a joke, even if it's yourself. I liked the OP's post. I saw myself in some of those entries, but so what? It seems that the more extreme one's position is on something, the more easily they are offended. Edition war? i didn't see that. Zin may have been more gentle on Gamists that the other GNS types, but GNS theory itself can sometimes be taken too seriously. Finally, she said straight away that this was tongue in cheek. That should tip folks off that she was at least trying to be funny. I actually learned a few things from her little list.
Relax, folks. Play the game. Play whichever game you prefer, whichever way you prefer, whichever edition you prefer. But please, if you're playing the game, play it to have fun.
