A party gathers information and knows about the existence of a settlement on road A that has a bridge, a road B with a bridge, bandits roam the area, and there's a ford at point C. The DM has a village planned out on road A, bandits planned by the bridge on road B, stream ford C between them has an old hermit planned, and the deep water D has planned giant leeches. Choosing one of A-D would count as a meaningful decision, right?
Does it stop being meaningful if there will also be an Ogre appearing along the way no matter which way you picked? (Does that cancel out all of the things from having chosen A-D and all of the choices made within that encounters).
