Good to write about what you love.
I wrote a paper once on the benefits of eco tourism in the Yucatan peninsula. It was pretty rad and I had to struggle to get it down to 16 pages. But it was fucking good.
That being said, I also taught an intro to video game development at UC Irvine for Summer Camp... It was fucking rad and I preferred teaching summer camp over writing that paper. Yay video games! Love making them, can't stand playing them! <3 geeks.
