I have the Starmen crest from Earthbound tattooed already. It's obscure enough that most people don't know what it is, and I honestly don't care for the opinions of people who think it's a dumb idea, even if it I do pass it off as something personal. And really, I have no problems with other people's gaming tattoos. I mean, I'll make fun of them for it, but only if I know they're comfortable with their choice. If it's something you wanted on your body, then awesome. If not, oh well. Go nerd culture. Go gaming culture. Have fun with it, it's not like it really matters.
