Hmm...this is what I would do. I'd have three different, very distinguished sections that represented each major console player. Each clerk working at the respective section is a fanboy of that console. Think of the tension, it would be beautiful. They'd be trying to convince customers to buy this and that...and then the other clerk interrupts, and everyone gets angry...
I would make it a bit more spacious than usual game stores too. You can't make too many games and places available for kids to play though, or else they'll never leave, so keeping that to a mininum is a necessity. I really enjoy Crash's idea of creating a sort of video-gamish interior (the mushroom kingdom, hyrule, etc.) I can just imagine walking into a store with these big red polka-dotted mushrooms, goomba figurines and the like...It'd be really fun and it would put gamers in an good mood...a buying mood.
