Many things.
Video game-wise, I am wrapped up in Day Z which is a frustrating, but very engaging game. But I also have my purchases from the Steam summer sale still kicking around to be played (Rage, namely) and a longstanding promise to play through the BlazBlue story mode.
Non video game-wise, I am nicely deep into a well-run Shadowrun campaign and am a long-time tabletop minis gamer (Warhammer, Warhammer 40k and a little bit of WarMachine).
