Usually girl, since that IS what I am, but sometimes the guy if I don't really like the girl design or if I am just playing for laughs. Or if I have two games from the same generation I'll have one girl and one guy, did that with Ruby and Sapphire. I played as the guy character in Fire Red for the longest time because I thought the girl design was ugly, but after a while I decided to give her a shot and she grew on me :p I didn't really like the girl design in DPPt at first either, but the guy is even uglier so... xD;
