There's actually quite a few good games under $20 now. Most of the Mass Effect and Fall Out games are under $20... The Dragon Age games are under $20. I'm pretty sure most of the Assassin's Creed games (not the newest two) are under $20. The first Borderlands is undre $20 and i'm pretty sure Borderlands 2 is right at $20. Elder Scroll games tend to have a lot of game play and are really cheap now.. Oblivion, Skyrim, etc. Dead Island... Left4Dead... both of those and sequels are under $20. I like Dante's Inferno. It's a decent game and I'm pretty sure I bought it for under $10. Note: I'm going off of memory of Game Stop pre-owned.
