Are you looking to finally unload your Game Boy, Game Boy Color, or any accompanying games? We'd suggest doing so sooner rather than later, because in a few days it will be too late (at GameStop, at least). As it turns out, the games retailer will no longer be taking these trade-ins as of April 7th.
If you own these systems, though, there's a good chance that you either a) sold them a long time ago or b) have no plans to ever sell them, so we're sure this is a non-issue, for the most part. Still, this makes us feel old.
