Yeah... this is not a game for completionists.
If you are worried about seeing every little thing, you are going to need to have thousands of saves, one before any particular choice. Choosing to go to a new place sets events in motion. Choosing to rest is a choice. Walking out of a town is a choice. Casting the friends spell is a choice.
If you need to know every flag, switch, and trigger in the game, you're gonna want to learn dig into their code or wait until comprehensive guides are built for you to plan your every action out ahead of time.
