Garrus Brokarian is a boss. ****es love bosses. And dat gravely voice makes ****** quiver everywhere. I don't know why some women like Garrus physically, but to each their own...I think it's largely due to personality. An attractive person whose a **** is a hell of a lot uglier than a fugly fuzz beast who is the funniest and best person to be around ever (example)...Just like how hunger makes everything taste good, personality makes anything look good...
In terms of physical appearances, Tali has dem hips. But I was more attracted to Tali due to several reasons and not just one. It's the package deal of personality, accent, backstory, hips, mystery, and the fact that she had that closet longing for Shepard.
Plus, she was one of my favorite characters in ME1, both in terms of gameplay (and outside of her god-like shield capacity, that tends to happen when 90% of enemies you face are synthetic) and her as a person. The whole quarian encyclopedia thing didn't bother me (besides what else is a person whose been stuck on a ship her whole life supposed to talk about?)..also, every alien except Garrus was an encyclopedia for their species......I also find intelligence EXTREMELY attractive (and engineers tend to be smart, last time I checked)...
and I have a glasses fetish...and her visor is like one giant pair of sunglasses to me...
and my favorite color is purple....
and she uses my favorite weapon: SHOTGUNS
and she names her combat drone :3
