I've been in the D&D game since 2nd Edition. I have run several 3.5 Forgotten Realms campaigns from level 1 into epic levels. I've run a number of classic modules converted to 3.5 as well. (See below). I finished running Princes of the Apocalypse and Curse of Strahd here on Roll20 just recently.
I'm very well versed in every Marvel game system released, from TSR's FASERIP system to the SAGA card system to the most recent Marvel Heroic Roleplaying from Margaret Weis. Likewise, I am an avid fan of Mutants & Masterminds 3rd edition and DC Adventures from Green Ronin. I can run any of these systems upon request.
I own the core book for almost every system you can think of, though I haven't gotten to play them all. Unused core books consist of Shadowrun 5th Edition, Cthulhu 6th Edition, Star Wars Edge of the Empire and Basic Fantasy. I would love to get my feet wet with those systems, even if it is just for a one-shot.
Take a look at some of my past campaigns.
