Almost everyday I play a bit of Fire Pro Wrestling D for the Dreamcast when I'm not too busy.
I also tend to pop in Power Stone 2 (which my fiancee really enjoys as well) and Worms World Party (which is beginning to frustrate me because she keeps beating me). A few times a week I'll pop in a fighting game here and there (Street Fighter 3, Street Fighter Zero 3, Marvel vs Capcom 2, Capcom vs SNK 2, King of Fighters '98, Soul Caliber, etc.) just to switch things up. Unfortunately, no one around here that I know is any match for me so I don't have any challenges. Weird, you'd think living in Japan you'd find plenty of people who were heavy into video games, but I guess that's not the case. Hmm...maybe it's time I start hanging out at Otaku areas to find players.
