It's the stuff dreams are made of. Just about every single Sega game ever released (plus some bonus "competitor's" titles), all secretly tucked away in a forgotten room at Sega HQ. Yeah. They forgot about it. And don't even know how it came to be. If that doesn't sum up Sega in the 21st century, we don't know what does. Ah well, point is, it's here, enjoy it. Would write more, but having browsed the shelves for ten minutes we're feeling a little faint...
