Rather than having expectations, i am excited to see what the game will show me. I love seeing things i haven't seen before.
So, i have a rough picture of where my choices may lead, sure, that's why i pick those choices.
But the way i think may be quite different from the way the dev of the game thinks, so the result i end up with isn't necessarily what i expect to happen. Which, to me, is fun too. The fun of discovery see?
Knowing everything ahead of time and planning for a specific outcome is... not my idea of fun.
I like not knowing anything and diving in completely blind, while trying to carve out more or less desirable outcome with whatever tools the game provides me with.
