I enjoy many games, including D&D (3, 3.5, 4, 5), FUDGE, d20 Mecha, and the games listed below. I also have CthulhuTech 1st ed, Cypher, Call of Cthulhu (6th ed), Spycraft (v1 & 2), d20 Modern, Mekton Z, Everquest (1 & 2), GURPS, Pathfinder, Final Fantasy 3rd ed, and Dungeon World.
I also enjoy tabletop games such as Fluxx (I have Cthulhu Fluxx), Cthulhu Dice, Betrayal at House on the Hill, Firefly, Risk (Metal Gear Solid ed), Munchkin Cthulhu, Tsuro, Elder Sign, Eldritch Horror, Arkham Horror, Call of Cthulhu LCG, Fortune and Glory, and others (I only listed some of the ones I have).
Video games are also a big list for me, but I won't list all of those that I have. It would just take too long!
I do other stuff, like reading, biking, swimming, listening to music, etc as well.
