I didn't find this one listed on the brick and mortar list:
GameOn - NY, Smithtown and Miller Place (2 locations).

Tristan and Brian are fantastic guys. (All of the staff is great, I just happen to know these guys the best). They were totally open minded when I created an Atari 2600 homebrew and they generously offered me shelf space and sold my game to locals. Can't praise these stores enough. Fair and more than reasonable on all sales and trades. Store is super clean and well organized. By far, the highest level of class when it comes to any retro game shops I've ever been to on Long Island NY.
