I have been doing Pen and Paper gaming for a number of years. I started out Playing AD&D, but didn't really get into Pen and Paper games until I played Shadowrun 2nd with a few friends. Since then I have played a bit of Hero 5th and 6th, D&D 3.x, Battletech, Shadowrun 3rd, Shadowrun 4th, Legend of the Five Rings 5th, and GRUPS 4th.
I also tend to collect books and read over them so I have a familiarity with a number of systems as well as having access to then as well.
