Chiefs fan. I was 10 when Montana was traded. Even though I'm pretty sure I was a Chiefs fan before that, the Niners were America's team during that era, and Montana going to KC removed any doubt about which team was my favorite. Here is the song of my people (a verse was added right after the vid was posted, though):
As far as sports games go, I pretty much like any sport, but I definitely prefer the ones that are heavily arcade style. So stuff like Mario sports games and Sega games like Soccer Slam and Beach Spikers. Currently my only 360 sports game is NBA Jam. I may pick up Blitz, but what I'd really rather have is a new Mutant League Football....which is supposedly coming out this year.
