This perhaps shouldn't come as much of a surprise, but America still loves its boxes. As reported by Gamasutra
, the NPD says that 90 percent of sales in Q3 2009 were attributed to boxed copies of games. If you're not so good with the math, that means only 1 out of 10 games was distributed digitally. That average drops to 79 percent if you lump together portables, PC/Mac, mobile, and smartphones, but that's still pretty darn impressive.
We have the same preference as the rest of the country, but only because we can't hang digitally distributed games from the ceiling tiles of our dorm room to give it a hip, edgy look.
