Gamestop completed its buyout of EB Games this week, making it the single largest game retailer in the country, as reported by Game Daily Biz. The merger creates a company with 4200 retail outlets worldwide, and expected annual revenues of $5 billion. Analysts expect the merger to lead to an increase in the used game market, which has recently been attacked by game publisher organizations as being detrimental to their business. The merger may well mean lower trade-in prices for gamers, too, which might in turn lead to an increase in traffic for online game trading sites as gamers flock to more worthwhile deals. And the news can only be seen as an indication that pre-release reservations and package bundles will enjoy unbridled growth. That could be problematic for gamers expecting to preorder an already very pricey PlayStation 3.
