Can you get any nerdier than this? Halo 3 gamer Moviesign proposed to his girlfriend Furtive Penguin in a game of Halo 3!
Instead there was a nice top-down view where he had spelled out a proposal in weapons. He then asked her to be his teammate for life.
She said yes.
Furtive penguin and Moviesign recently moved from Indianapolis to Chicago where she (penguin) is a copyeditor and he (Movie) is a graphic designer. They haven't set a wedding date yet. As furtive penguin said, "We're waiting to see what the release date is for the next Halo game. We don't want any conflicts."

Maybe they'll do something like this for their wedding cake.
