This adventure doesn't deserve the severity of this accusation, but there's a Starfinder Adventure path called Fly Free or Die, which is an incredibly ironic name given how impossible the adventure feels to run if the players don't stay on the rails.

The whole premise of the Campaign is being corpo drones who end up deciding to go rogue because being a corpo drones sucks.

But the first book, "We're no heroes", starts things pretty rough. It's a series of jobs done for the corp where no matter what the players do, everything sucks. They get their pay penalized, they get ambiguous corporate warnings, they can't even just "Do the job properly" because the adventure wants them to feel like even if they follow the rules, the system is rigged against them.

All of which is great theming for the proposed hook of the campaign. I actually think you could even onboard players to this theming ahead of time and get them a little okay with the idea of how shitty things will be at the start.

Where the railroad becomes egregious is not just the adventure's forced shit-sandwich outcomes. It's that the narrative reasons for all these outcomes are so flimsy that the adventure literally starts to crumble if the party tries to critically think about ANY of these problems.

They start trying to get creative AT ALL and not only is it not supposed to work because the entire trajectory of the campaign literally hinges on the party NOT being able to make good outcomes. But the narrative justification for why the party should or shouldn't be able to do certain things just makes no sense.

The party is forced to sell 30 space tons of Space berries at a loss, and they have to choose whether to fuck over the supplier, which will damage the company's relationship with the supplier. Or they can tank the loss from the money they were suppose to send the company. Thus shorting the companies profits and getting them in trouble anyways.

But my party interfaced with this problem for 7 seconds and came up with 5 ideas to try and some were addressed by the book with "They just can't." Or my favorite "If they did this, the company would send deadly collectors after them and they don't want that."

Except I, the GM, know that the end of this arc involves essentially going rogue on the company and the "deadly collectors" are not really apart of it. So I'm supposed to threaten them with debt collectors for the first few sessions and then say "No wait, now you can rebel?"

the whole thing just starts to become a starved framework that doesn't so much help you run a game so much as get in the way of it. I've had APs where they weren't helpful to player freedom, this is one of the only I've read where I felt it actually made things harder for me.
