After years of on and off playing star wars, and DnD 3.5, I've started running games for my group, after the first one they couldn't get enough (apparently my niche in our gaming group is investigation and horror). I now have a Modern D20 paranormal investigation game (think call of Cthulhu and Supernatural but also my own imagination running the show), a Cthulhu d20 game set in the 1920's of the same universe as the modern game, and I shall be starting a Wild Talents game set in a parallel comic-verse of the modern game.
Usually try to run the Modern game every Saturday or when-ever someone else doesn't want to GM (they really like the paranormal games and any other games have taken a back seat recently). The two friends who are in the 1920s game actually came to me wanting me to run it as I had the book and they love wearing suits and fedoras (they will on occasion arrive at our games dressed for the occasion XD), wild talents game will probably be the same schedule as the 1920s game (whenever during the week starting at 1 in the morning.)
...I think that's all of 'em... oh and I play in a Monsters game over skype every other week.
So I guess I'm at 4 games now, 6 if you include the games that don't usually get a lot of love.
And I believe all this kicked in during the fall of 2012.
