"If you put your mind to it, you can accomplish anything."
In the first film, Jennifer points out that Doc always says this. Marty uses it later in the movie to help convince George that he can stand up to Biff and win Lorraine.
I would love to hear Christopher Lloyd actually say this great, inspirational line in the game. And failing that, it would be a nice parallel to have Marty say it to young Doc. (Though that would be one if those goofy predestination paradoxes...)
What do YOU think? Worthy of inclusion?
