Seriously, that looks fucking awesome.
I guess it loses some of it's meaning when so many people say it but I would seriously buy all my game purchases from you if I lived near (unfortunately, Europe isn't). Even if it would cost a couple of bucks more. Too bad you don't want to do a web-shop with it, or I could buy DS import/pre-order games from you.
From the look of things, you have a lot of factors covered. I agree with people saying you need quality employees who don't push people, just let them be but are there for them if needed. People that know what they are doing, are neutral, that can find whatever you need easily, that are helpfull and non-intimidating.
I would love to see such a store for games where I live. Where the ambiance is relaxing, where you just can check out stuff with ease. Tournaments (friendly ones) and the game lounge and living room are great ideas. Especially on days when a big game launch so you don't have to wait hours for closed doors or just in line but can relax (after you've taken a number). Just set up a soda machine and put an extra couch and it's perfect.
You mentioned something about the accessability for non-gamers to browse and such. I just thought of something that perhaps could be usefull.
I think it would be a good idea then to include some sort of "featured" game section in a number of different categories with additional info and a monitor displaying them. Say, family oriented games that would be great choises that the whole family can enjoy (Guitar Hero, Wii Sports etc). Or top x-mas choises, games for children (parental choises) and so forth.
I think it would make browsing for a lot of people easier because they probably don't know left from right beforehand for choosing a game and will rely on what the child want or the boxart/commercial or what the employee suggests.
I hope it works out greatly for you but I think you'll do just fine.
