Uh, where to start?
I've been on Roll20 for a really long time. I tend to play a lot of the non-standard systems like Palladium RIFTS, Stars Without Number, and Pokemon Tabletop United, but I'm more than familiar with classics like 3.5, 4.0, and Pathfinder. I've been a GM and a player of all of these games types, and I guess it's safe to say that I have an addiction to tabletop games.
The characters I make tend to have convoluted story aspects (Like a Changeling Cleric who lives in fear of the party knowing their true race), and usually fulfill a supportive role. Be it someone who takes damage, mitigates damage, or provides useful skills outside of combat.
