That's what I was not clear on. I was under the impression that any node addition would gain "Experience Points." How can I gain lose XP
As far as PM not being a game, it's been made into a game with the concept of stating a player and then working to gain experience, leveling up unlocks new spells. It's more about perception, how you look at things, then it is about wether or not PM is a game. From a certain PoV it is a game, while at the same time looking at it another way it is not. Neither viewpoint is entirely correct or incorrect, they "both simply exist."
