GameStop is to start accepting retro consoles and games as tradeins. It will then sell them via its online store.

The program will cover consoles from Nintendo (NES, SNES and N64), Sega (Genesis and Dreamcast) and Sony (original Playstation) plus associated games and accessories. GameStop already accepts several later consoles.

It’s a test program at first, with the consoles and games accepted in the 250 Gamestop stores in the New York City and Birmingham, Alabama markets. A nationwide rollout will follow if all goes well.

The consoles and games won’t go on shelves in those stores however. Instead they’ll only be available to order online for delivery or for pick up at a local store.

Trade-ins are available from next weekend, but it’ll be a couple of months before the consoles and games go on sale. That’s partly to allow time for GameStop to ship the products to Texas where it has a dedicated center for testing used products and repairing them if necessary.

The delay is also intended to make sure there’s a decent range and stock level of games when they go on sale. GameStop estimates that adding games from the older consoles will expand its range by around 5,000 titles.

There’s no official word yet on the prices GameStop will pay for the consoles and games or the prices it will charge when it resells them.
