I've been gaming since I can remember. (Over 40 years) I've played RPG's, board games, tabletop miniatures, and video games. I haven't played RPG's in a while and I've been looking to get back into some of the ones that I remember and loved.
As a GM, I prefer to use the rules as a guideline. I'm not saying I ignore the rules, but I'm very willing to modify or drop a rule if I think it is going to interfere with the story and feel of an adventure. So, if you're a person that lives and dies by the rules.... my games are probably not for you.
