My first tabletop roleplaying game was Vampire: the Masquerade in 2004, and I have since played many, many more. I have also participated in three LARPs: Vampire: the Masquerade, an oWoD crossover (Vampire, Werewolf, and Changeling), and Exalted 2e.
I have created a number of API scripts and character sheets, however I am no longer actively developing on Roll20. Feel free to drop me a PM or leave a comment on my talk page, but be aware that I may not answer quickly.
