In October Telltale Games will join other Wii publishers with the release of Back to the Future: The Game. It'll be available for $19.99 and opens the door for more upcoming releases that have been announced by the company such as a game based on Jurassic Park and Law and Order.
The company is hoping that with them being able to release the games on disc instead of as downloadable entities, they'll be able to avoid some of the issues they've had in the past. More space via a disc release allows them to clean up their graphics and voices.
Back to the Future is also available on PC (with a Collector's and Deluxe Edition), PS3 and iPad.
