Remember all of those games that you played when you were a kid? Now you can go buy them again. Starting today, GameStop is selling retro games and systems online and in its stores.

Games are available from six consoles: Nintendo 64, Super Nintendo, Nintendo Entertainment System, Sega Dreamcast, Sega Genesis, and the original PlayStation.

Be cautious, however. All of the games being sold in this new program are pre-owned. You’ll have to turn to Ebay or another retailer for any mint-condition factory-sealed software you’ve been looking for.

The most expensive games include:

• Conker’s Bad Fur Day for the N64 — $79.99
• Suikoden II for the PlayStation — $89.99
• Cannon Spike for the Dreamcast — $79.99

This marks the beginning of vintage hardware and software sales for the store, which often phases out old games in favor of newer consoles. The store stopped selling PlayStation 2 games in 2013, but began again in March because of high demand.
