Great Scott! It seems that Telltale are going to be producing a Back to the Future game and it's going to apparently follow the same format as other Telltale games (i.e. five monthly episodes). They've even managed to get Christopher Lloyd back to do the voice acting for Doc Brown, now if only they could get Michael J. Fox back for Marty McFly!
The game is set to be released sometime after October 26th which commemorates the 25th Anniversary of the trilogy.
