I hadn't heard this, thank-you for posting.
Are you in this region yourself? Just wondering whether this would be a bummer for those hunting for older used games or if there are plenty of smaller stores that do that. I guess online shopping negates the necessity but I like poking around for stuff in person.
Like @krummi said, GameStop has competed with small local chains for years now and I haven't seen those chains really reduce their store count much in recent years. Those local chains will still continue to support the used games market. In addition, online auction sites have for a long time been a much cheaper and often more efficient place to sell and buy used games. Finland for example is one of the most sparsely populated countries in Europe, so the convenience of being able to ship games from household to household via mail us often more convenient than going to a store.
