is there anything attractive about a gamer?

[Esquilax]

I should clarify; I don't think that being a gamer makes you unattractive. I just don't see why it would makes someone think they're attractive.

Perhaps consider the possibility that people might choose their attire in ways that aren't based around making themselves more attractive to other people. I don't know about you, but unless I'm specifically going into a setting where I need to look presentable I just want to wear clothes that are comfortable for the setting I'm in: I don't owe the rest of the world a designer look. I wear t-shirts and jeans a lot, and some of those shirts have game or comic characters on them, and that isn't for the benefit of everyone else.

Like those guys wearing the video game shirts. I have never seen someone wearing a video game shirt and though that I could relate to them even on a superficial level. I used to be an avid gamer before I got tired of the repetitive structure of video games.

Seems like a problem with you, judging people based solely on a single look at their appearance, than with the hobby. Maybe try not extrapolating a person's entire personality off of the fact they like Megaman next time?
