Xbox 360 is a wonderful hobby ;) my husband and I both love video games.
One hobby I have that turns me into a nerd/geek in the eyes of the average person is costuming. I'm in the 501st so back off OK! :) my geekness is justified! So I make star wars costumes, it's really fun to look at a picture of something and recreate it. Find the right materials and turn normal things into something awesome. I don't just make stuff for me but also when Halloween rolls around I make the most awesome costumes for my kids :)
Fishing is fun, photography, and I write stories as well
