With the encouragement of Secret Fawful, I am posting this here. Please hold back the flaming darts if a thread on this subject has already been posted, but I wanted to share some episode ideas, and would love to hear some other ideas from the community, as well.
This idea came about while chatting with SHODANFreeman on Raptr the other night: Doctor Emmett L. Brown has rebuilt and re-engineered his DeLoreon Time Vehicle. Not only can it travel through time, but now, it can travel through space, as well! In the exciting first episode of Back to the Future: The Game, Marty McFly becomes the first test subject to a new breed of time travel when he is sent back to the year 4 BC. Shortly after witnessing the birth of Christ, he is mistaken for "the Messiah," and using instruments from his own time, must perform would-be miracles for the captivated populace. Find out more when "Back to the Future: Episode 1: Christmas is Canceled" arrives this Winter!
Some of the instruments that Marty might use include: hover board to perform walking on water, or if it does not have adequate power, hover shoes from the year 2025 AD. Modern Medicine to perform the healing of a sick person (resurrecting the dead might be a bit far fetched).
I could totally see this playing into future episodes, too. Say, Marty's effects on the past cause the Church of McFly to be founded. A church which features murals of Marty and the time traveling DeLoreon. It could be a nod to the obsessive fans that treat Back to the Future as if it were a religion, or something.
Here are a few other episode titles, which may inspire a few ideas:
Episode 2: How I Swiped Thomas Jefferson's Autograph (1776 AD)
Episode 3: Roman Holiday (509 BC)
Episode 4: Post-Apocalyptic Times at Hill Valley High* (2085 AD)
Episode 5: Erasing Episode 1: Christmas is Canceled
Expanding on that Roman Holiday idea a bit: One of Marty's ancestors could be a royal adviser to the King of Rome, and who do you think would be the King? An ancestor of Biff, of course. He was so incompetent that he needed a royal adviser at his side at all times. Marty's Ancestor: "I'll have those battle plans drawn up by tomorrow morning, Sire." Biff's Ancestor: "Okay, not too early, though, I sleep in on Sunday!"
* Post-Apocalyptic Times at Hill Valley High is a nod to Fast Times at Ridgemont High, if you couldn't tell.
