You see, I only play free form games. It's how I learned D&D. I even built my first game as a Fallout Knock-off RPG. I find that when you build the game around the mentality of those who play, you get more fun and less argumentation with the DM. While I wouldn't say there are LESS rules (sometimes there are more) I like not having to lug around books. Just my character sheet and dice. Sometimes not even that if we really wanna wing it!
