Some great points Roland and thanks. Another great point is that you don't even have to do quests to enjoy the game. Lots of people even choose to play with no traders since they prefer a more nomadic unguided experience.
I can empathize with those that truly don't like dungeon POIs because of their linear pathing. However, keep in mind that linear path is what allows level design to deliver a paced experience with ups and downs much like how movies and books tell a story which is a fantastic thing.
What other open world fully destructible voxel game on the market gives you such a mixed bag of levels/experiences (non questable, remnant, etc.) to choose from?
