Taking a cue from the subject matter of Back to the Future: The Game, Telltale and Sony are going to begin selling the episodic adventure game in an old-fashioned manner: boxed copies in stores. Telltale has 'expanded' its publishing agreement with Sony to include retail games, the first of which will be Back to the Future. The disc version will be released this October, at the same $19.99 price point as the digital version.

The agreement isn't exclusive to Back to the Future; Telltale now has the option to publish retail versions of any of its PSN games. To date, that includes Puzzle Agent, Strong Bad's Cool Game for Attractive People, Tales of Monkey Island, and Sam & Max: The Devil's Playhouse.

GamePro reports that Telltale has also signed on as a Wii retail publisher, also planning a retail version of Back to the Future this October for the same price. Previous Wii retail games from the developer, including Sam & Max seasons one and two, were published by other companies.
