Joel Dreskin from Telltale Games Told LapG when we asked about if they plan on using the same storylines from the movies.
"Our games will be a completely new story. The storyline will start shortly after the time period from the films." Joel Dreskin said.
This was really good to hear, because i was worrying that they was going to use the same storyline as the original back to the future movies. This would have been boring to me, because i would have already known the ending, and how the story of the game was going to unfold.
