I'm Albert. I got a Roll20 account because it gave me the opportunity to ST a V20 game for an absolutely amazing group.
For games, I'm primarily interested in the New World of Darkness / Chronicles of Darkness, but can play (Old/Original) World of Darkness too. I have a lot of books for both of those, and am fairly confident I can play almost anything in either of those, in any edition. I'm willing to learn anything I don't know yet.
For other games, I'm familiar with Exalted, GURPS, Weapons of the Gods, Nobilis and various D&D-alikes. I'm always willing to learn new systems, too, if the game's otherwise appealing.
As an ST, I've so far been mostly into heavily-political games. Personal interaction in a living world based around a particular theme and mood is what I enjoy doing. If there's issues or stuff related to plotlines I prefer talking things out out-of-character first: I think that in-game actions never really solve out-of-character problems and are, at best, an abusive stopgap. I try to be flexible with players: I want people to have fun first and foremost.
I live in the UTC+1 time zone and work full-time. This often makes things hard to work out with a lot of North American players, though not impossible.
