There is no change to Marty. He has to be the constant. He comes back a few minutes early to warn doc but the car dies meaning he doesn't cross his own path.

Docs path changed but he knew he had to stay the course to make sure that everything the was meant to happen happened.

Betting on a game and even winning big is not gonna change the outcome on any other game in the near future. If any major athletes came from that town in the 80s or later it might be less accurate at that point if not it likely wouldn't change much.

No reason for them to charge more than $70. It's gonna have online where they will sell stuff for years and more than make up their profit.

Or they can split the game to story mode only for people like me that don't have the time for the online. I'm not looking to pay a for a game that has a huge portion I'm not gonna touch.

Otherwise I probably will wait till it goes on steep discount.
