"Why would you want to play your adventurer game as a mercanary or pragmatic explorer? You get politically correct paladin or evil spawn of satan. Choose now."

A good writer wouldn't even need 40 different branching paths, but a viriaty of well written dialoge options to get you to the three or four paths that they can control.

But making this is a lost art:

I am going to help you

I am going to help you (lie)

I am not going to help you - >

Fuck you

This is why not helping you is a good idea (Persuasion)

You are retarded (Knowledge)

Die (Attack)

And the retards who love 5e eat this shit up. They even took out alignments and racial stat bonuses, further enforcing your choices don't really matter.
