While I am new to Roll20, I have been a player and\or game master in "Dungeons and Dragons" products since mid 1978. I have been involved in the creation of multiple home brew worlds\campaigns for near as long.
While I am open to playing other game systems I prefer at this time to keep it to D&D 3.5 and Pathfinder. I am currently learning the ropes of Roll20 Campaign building, but am hungry to try the system as a player to see it in action.
Best days for me are Wednesday evenings (4:00 PST) or Fridays (pretty much any time).
