I saw my first Play N Trade last year, at a local mall. Since then, they've been growing at a pretty rapid pace for what appears to be a small franchise, adding 3 stores in my town alone.
Play N Trade is a typical game store in the GameStop model, but unlike GameStop they focus on retro systems and trading. They even sell their own hybrid NES/SNES console, the Retro Duo, which plays both North American and Japanese games and even has an S-Video output (for the SNES). I bought one last week, and I'm quite happy with it so far. There's also a combination Genesis/SNES model, which I haven't tried (why couldn't they make an SMS/Genesis model?).
They also emphasize community-building, with frequent game tournaments (Guitar Hero, Super Smash Bros, Soul Calibur, etc.).
They seem to be a great brick and mortar alternative to Gamestop. One store even had the balls to open up right across the street from my neighborhood GS. Anyone else have any Play N Trade experiences to share?
