Been a while since I've had the opportunity, but especially in university I played a lot of D&D (3rd ed/3.5 ed), from time to time some Call of Cthulhu and d20 Star Wars as well.
I've been running Shadowrun (5e) games for nearly a decade now. I also really like Forged in the Dark systems, I play a bit of D&D 5e, and I'm currently running a short campaign of a game called The Spire.
I play quite a few:
Star Wars d20 & Edge of the Empire
Warhammer Fantasy 4e
Warhammer 40k Dark Heresy 2e
Shadow of the Demon Lord
Mork Bork
Legend of the Five Rings
Zweihander
Pathfinder 2e
