Well, according to some research done by Gamasutra, in the United States the chain controls 21% of the games market (excluding accessories & PC software, whose data was "impossible to extract without resorting to outright guesswork"). That's...well, it's not anywhere near as high as I'd have thought.

You can check out the full report below, which reveals the number of stores per 100,000 Americans, and the fact that the state with the highest density of GameStop stores is...Delaware.
