GameStop recently pulled away a bit more of the veil covering its "Store of the Future" initiative, releasing a whole mess of details on how its digital distribution storefront functions. A new page on the retailer's site explains the purchasing process for the site's downloadable PC games (of which there are currently over 2,000), as well as a handful of free trials and, in the near future, add-on content.

The page also reveals that XBLA content will soon be sold through the website, which gives the purchaser an unlock code which they can input into the Xbox Live Marketplace to retrieve their content. It's pretty straightforward stuff, but we're still looking for the page that explains how we can trade our downloaded games in for store credit. If anyone comes across it, would you please let us know?
