Green Pixels: Plunking down $50 for a brand-new game can be a gamble -- it's a lot of money to pay for something that you could end up hating. However, most games don't stay full-price for long, which is why we scoured the inventories of four major retailers (Amazon, GameStop, Target, Walmart) to find a slew of great titles that are now priced at just $20. For the cost of one freshly released game, you can buy two older titles and still have $10 left to spend on snacks. (And we all know the importance of snacks.)
