Everything related to gaming, pretty much, in addition to programming. I'm also pretty good at a lot of games. Here in Finland, I'm ranked #11 in Super Smash Bros Brawl and #2 in Tatsunoko vs Capcom, and am or was some of the best in Super Mario Bros, Worms: Armageddon, the other Smash games, Stepmania (keys, 1 hand) and F-Zero GX. I also speedrun some games, including Ocarina of Time, Link's Awakening DX and Spyro 2.
