I talked to someone working at a game store (gamemania in the Netherlands). The stores also buy and sell second hand games. I commented on the amount of fifa games on the shelves and they told me the storage in the back just has massive stacks of every fifa game of the last 10 years or so. Apparently they will literally buy every functioning game you want to sell them.
The chain is also close to bankruptcy, probably not related. But it’s a shame because I really do like walking through them and looking through the games they have. They actually have xbox360, wii and ps3 games on shelves.
