If you’re going to sell your old videogames? Do not try to sell old sports games. Ever. No one is ever going to be looking for vintage hockey games. No one is going to want Madden 2011, when any future Madden has been released. Deal with the fact that EA has bilked you for 60 bucks on what should have been an expansion pack, and stop crowding Craigslist with bullshit no one will ever want in a thousand years.
