Guys, an advice, what would be the best Blue ray set for the Back to the Future Trilogy?

NOTE: The 1st timeline ends when Doc goes back in time from 1962 as shown in the "The Doc Who Never Was" Comic story, but that story has framing sequences set during "Back to the Future Part III" So i didn't placed it for now.

Ok so no plans on a Blue Ray re-release of Back to the Future is in the works, so, I'll just Use the films' digital release.

As for now I'm trying to see if I can fit "Emmett Brown Visits the Future" and "The Trasformers/Back to the Future"

So for now I'll say that this is the order I'll go with.

Back to the Future
The Trasformers/Back to the Future #1-4
Back to the Future #4

Yeah, the Transformers crossover is a weird one since it plays off the events of the first movie. Well, technically the beginning of Back to the Future 2 is slightly different to the ending of Back to the Future. Maybe you could work with that or something.

I think there's theories that the first film played out multiple times or something - it's been a while since I saw them. Maybe the Transformers crossover could be a prequel too.

Also considering how after the Earth Special, Brown travels to 1951, shouldn't the whole ghostbusters universe cease to exist?

Same with the Tarantino-verse as after 1882 he goes to 1990 and then to 1988, basically stopping the TV before Recevoir Dogs can begin?

Maybe certain timelines, for whatever reason, carry enough weight to continue existing after time alterations. Crossing the streams was apparently a multiversal event, who knows what effect on that specific timeline it might have had? The Earth Day Special could also be canon to multiple worlds or the Elon Spengler skit could be exclusively canon to Ghostbusters since it's not directly linked to the main plot.

As for Tarantino, eh, who knows. It's a silly comedy film, the cameos are just something we've got to work with.

I'll go with this, since Cybertronians exist in BttF I'll mix both the franchaises rules of Time Travel.

As stated in Beast Wars if you go back in time nothing will happen as long as you don't change smt, so Brown going to 1951 to pick up Einstain won't change nothing. But it will create a new alternate timeline, but instead of everything changed, it won't change anything.

for the TV while Emmet gets found out he is able to cover what he was doing, so actually not changing anything, so when he'll go back in time, nothing will change as he didn't change anything.

Hope it's clear haha.

But to keep it short, yes if you go back in time a new timeline gets created, but if nothing gets changed in the past, the past events will get carried in the new timeline.

If we take the cameos at face value that means Back to the Future and John Wick share a universe

Ah, I see.

Back to the Future -> A Million Ways to Die in the West -> Tarantino -> Payday -> John Wick

Yeah, I imagine we're not going that far.

Do you ever plan on doing a Tarantino timeline?

There's also this... Jay and Silent Bob's Super Groovy Cartoon Movie. It's not set in the main View Ansewinverse timeline so there's no commitments for that.

This is probably how I'd do it based on that.

So the franchaises connected are Ghostbusters, the Payday and Tarantino Universes?

Tbh Idk if I wqould consider them, probably yes, I'll put them in the simplified order, but IDK if i'll put them in the detailed timeline.

Also I basically have to put in the simpliified order the whole ghostbusters, thanks to the multiverse crossiver.

I wouldn't bother including everything else in my opinion. Stick to Back to the Future for simplicity.

So I could place Ghostbusters alongside BttF in the years they happen, the TV with the cameo of Brown in it thanks to the altered WWII events, the Payday Universe? IDK. What is the connection?

this is way more reasonable.

I would still break it up by timelines like the wiki does. It'd just get extremely confusing otherwise.

In other words, the Transformers crossover is the real continuation of the 1955 portion of the Back to the Future movie. The ending of the film is actually set in a separate timeline that branches between 1955 and, I guess, 1974, leading to the Cybertronians not showing up. It actually works quite well like that, I think.
