I didn't vote, but I think my opinion seems to mirror the rest. Jaws yes, BTTF no.
I think you just need to look at where the meat is. On Jurassic Park the meat is literally in the dinosaurs. The characters, the humans, are fine, but they're just not essential. We're here for the dinosaur movie.
Jaws, same thing. The humans matter, but when people want the game they're asking for a big ass shark toy, they want the music, they want the shark eating motherfuckers. If anything a Jaws game that didn't use the movie at all would probably be better. It's honestly a slow film really, very few genuine action scenes. Skip all that and make a cool shark game with the Jaws name to sell it and you're gold. The Jurassic Park animation team (I think Keith shouted out like 6 people) has clearly demonstrated they could animate a shark.
BTTF has the car, and that's cool, but the story is really about people. No people, nothing compelling. I don't know that it's a great pin license, probably, but only if you really had all that access. All the scenes, all the lines, all the faces, nothing held back. We got away on Alien without Ripley, I think we totally pulled it off. But BTTF without Doc? Please.
My feeling is there a million license ideas out there. Or thousands at the very least. Pick one that either gives you a great hook for an original thought (Jurassic Park, Jaws) or only pick one like BTTF if they're giving you the whole cake, and letting you bring your own ice cream. If you're limited? Pass. Like, Wonka, if you're stuck with the slot machine art package and a family that won't let you use the word brats? Just walk, make something else. Why compromise?
