2 games right now, both of them are Zelda games: OoT and MM. I've been practicing glitches, sequence breaks, and other techniques for speedrunning, and I've attempted some speedruns of OoT so far. I may attempt MM, but I'm considerably worse at the MM tricks compared to the OoT tricks. I currently have an MM practice file where I've completed the Woodfall and Great Bay Temples.
Replaying Twilight Princess (currently avoiding City in the Sky), recently downloaded Team Fortress 2, and I'm also currently playing Child of Light, which is fantastic. Also, lots of League.
