I still haven't played the video game. I think I can probably find it cheap, now. Hmmmm..
What doesn't make sense to me is this. Since Marty came back to 1885, doesn't that mean there is now TWO Deloreans present in 1885? The one Marty used to get back to 1885 in, and then the one that stranded Doc Brown in 1885 from BTT2....if so, then why not use the gas lines and gas from the one Doc Brown gets stranded with to repair the one Marty damage during the Indian chase? Then simply leave a note on the one that Doc stores in the cave for his 1955 counterpart to find with a note to add on a gas line along with the tires, and the other repairs, in 1955?
Damn, that thing gave me a headache reading it!That happens with pretty much all time travel movies - it can drive you crazy if you think about it too much! @_@
Soon after the first movie came out, someone wrote an interesting essay called "The Other Marty McFly", about how the Marty who grew up in the successful family was able to return home quickly because Doc - who now knew what was going to happen - made sure to have extra plutonium in the car. But the second Marty went back to the future of the first Marty, where his family was a bunch of losers.
ETA: Here it is if anyone wants to read it, it was published in the July 1986 issue of Starlog:

Nope, it never bugged me in the slightest. I love how it just started off with them being friends.It's strange... The Marty/Doc relationship is shown to be a very strong bond in the first film, hell through out all three. But does it ever bug anyone else that we never see exactly WHY these two individuals actually are friends? BTTF just starts out with teen Marty hanging out with Doc. We see he has access to Doc's home, is friendly with Doc's dog, but how did these guys meet? It's not something that ruins the films by any measure, since comedy trumps all logic in the films, it's just something that sticks out to me. Unless I am not remembering something?

t:Oh I meant, why did bring up Lord of the Rings here?
Lord of the Rings? Or Back to the Future?

It seems to go against everything the Doctor learned about the dangers of time travel and seems like a glaring plot hole.
