Whenever I'm at a games store or convention, I can't resist the urge to look for stuff I did art for. Sometimes it's well displayed and I am happy. I get a giddy little feeling in my stomach. "I did that" I want to say. "Look! ... That's my name!" - Luckly I have some self control and can often resist the urge. Try and play it cool.
The flip-side to this adrena-pride however is the bargin bin. I approch these like a 7 year old child taken to an open casket funeral. Fear and dread dripping from my bones.
