Not much to say, really. Been playing tabletop RPGs since I was 12. Started with OD&D (elves were a race AND a class!), graduated up through the versions to 4E, decided to develop my own universal RPG system- and here I am now after almost 30 years.
I'm cool with any of the traditional systems I listed, but thanks to a great gaming group I was part of for twelve years I have come to dislike levels and classes. Now I prefer ala carte build-your-own systems with a simple core rule set (much like my own RPG, Sin Nombre).
