Before TTG published episode 01, there has been a lot of speculations about the return of the delorean. It was explained in the first episode but there has also been a lot of criticism about the story of duplication.
It was stated that the delorean was destroyed in BTTF 3 and by preventing paradoxons it was also not possible for Doc to borrow or steal a Delorean from any other time we saw in the movies.
Either Doc built a new one or.... well we follow the dupication-theory (which brought a new element in the BTTF universe).
But I think there could have been another possibility and thus episode 01 would have started like this:
October, 27th 1985 - 12.04 pm
We see the destroyed DeLorean on the train track. Marty and Jennifer appear. She agrees that there's not much left, Marty finds the picture of Doc standing beside the clock and is sad about the fact that he won't ever meet him again.
Suddenly the bells of the gates at the railroad crossing beginn to ring when the gates start to close.
Within seconds the reentry of the timetravel train boosts Marty and Jen away. Doc. Marty. It is steam-powered. Clara. Jules. Verne.
Where are you going? Back to the future? No, I've already been there.
The train starts to hover, goes up in the sky and turns around.
So far the opening is just the same as the ending of BTTF3, but ingame.
We see Marty and Jen looking into the air when the train accelerates and vanishes into the wormhole just leaving firetrails behind when suddenly there are the bangs of the reentry at the railroad crossing and a Delorean appears streetwise, slammes it breaks and stops on the road. The outside is frozen, vapour is raising into the air. It is the Delorean but with the whitewall tires from the 50s and the upgrade on the hood. It is clearly the same one that Marty used to travel to 1885.
Zoom to Marty's face showing wariness when he says: "What the hell is going on here?"
Then the logo appears: Back to the Future: The Game.
While the credits appear the camera moves slowly across the remaining parts of the Delorean on the train track, showing it from different angles. As the credits are over the camera stops at the second Delorean with the 1955 parts. The Door opens and we see Marty wearing his clothes from 1985A getting out. He just looks down the street moves his hand through his hair and says "Great. Everything looks great" before he gets back into the car and drives away. Marty and Jennifer follow the leaving car with their eyes until it gets out of sight.
From now on we have control of Marty.
Later on in the game we find out that because Marty prevented Doc from being shot in 1885 and the tombstone vanished there wasn't any reason for Marty in 1955 to travel back to 1885. So 1955 Doc repaired the Delorean from Delgado Mine and Marty travelled back to 1985. That's the reason why there is a Delorean in Episode One and the destroyed one on the train tracks is not the "last one". Of course we have to fix the problem that there are now 2 Martys roaming around in 1985.
What do you think of that?
