Not exactly.
It's two pages, compared to the tens of pages it's based on (D&D).
If you read the first section, you should know that most of the improvisation comes from creating your own abilities.
If you can't handle that, and obviously from your sentiment towards the topic I can see that tabletop rpgs are just not for you.
Now saying this, I'll assume you haven't encountered a game of D&D in person so correct me if I'm wrong... but why would you bother assuming so much from a glance when you have no experience in the subject?
