GameStop has held the market on used games for a significant amount of time, and while the metrics and math of the value proposition of both trading in and buying used games may be unclear, it has been a big portion of the company's strategy, and in a few weeks it's about to get a big overhaul.

The company has announced a new initiative to revise its trade-in system that will simplify its previous plan, and working in the benefit of consumers to give slightly more money toward trade-ins. Originally using a tiered system with up to 10 different prices for a game, the new initiative from GameStop will simplify this to up to four, and ultimately giving customers up to 20% higher values for game trade-ins.

Slight variations on the pricing will still exist, such as customers receiving slightly less for cash trade-ins versus getting store credit, and for the higher trade in values/lower sale prices for members of GameStop's PowerUp Rewards subscription membership. However, the "average base value" of trade-in games will see a slight increase across all titles, with the new trade initiative taking effect at GameStop retail stores on August 18th, 2014.
