I'm Jon. I've been reading Destructoid since at least August '08, but only decided just recently (as of May '09) to start being an active community member. If you want to know more about me, feel free to read my intro forum post.
Long story short: I'm a grad student who enjoys video games and video game related news, but doesn't get around to actually play them that often. That's probably why puzzle and rhythm/music games are my bread and butter, since they're pretty easy to pick up and play. JRPGs used to be #1, until it dawned on me that I no longer have time to hunker down for hours at a time.
To anyone with a PS3 and a love of puzzle games: I bet you I could kick your ass in Puzzle Fighter and Critter Crunch with a probability of 50%. Game on!
