EVE Online has had a staff economist for about a year now, I think, as mentioned above. I play EVE, and a large part of my time in-game is spent making economic decisions: what to manufacture, where to buy raw goods cheap, transportation costs and risks (20 jumps through low-sec space to buy low might be worth it, or I might lose my ship and all its fittings)...and, yeah, it's really tedious but still somehow fun.Link
The great thing about EVE's economy is that, with the exception of skill books and basic blueprints, everything in the game is player-created -- from the lowliest ammo to the most gargantuan battleships. So prices can fluctuate wildly across regions, and wily traders (with better ships than I can fly) can make mucho moolah off of those shifts.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
