BttF: The Game

I'm a bit worried about Back to the Future: The Game, being published by Telltale Games.

Marty's voice is okay, but the trailer leaves much to be desired.

1. The voices are really out of sync. It was okay in original SCUMM games, where it was just basically flapping mouths.
2. Didn't Marty destroy the speaker in the first ten minutes in the original movie?
3. How did Doc rebuild the DeLorean? After all, it was destroyed completely by a train in the third movie, and DeLoreans aren't common.
4. Are they just going to write off the fact that Doc was married to Clara Clayton and had two kids?
5. Are they going to acknowledge the fact that Doc's house appears to be in a fairly commercial part of town? After all, it did have a gate in front of it (as was seen) but in the movie, you'll see that a Burger King is next to it. I imagine that the Burger King won't make the cut in the Game, but I am going to be not happy if it's set in a residential neighborhood.
6. Are they going to write off the fact that Doc built a flying train that could time travel?
7. In fact, are they just going to write off that entire scene of Doc coming back in the train?

After all, it does involve time travel, so a canonical time altering could be done...
