It's perfectly possible to create an interesting, non-banal open world RPG with a well-told story.
And awesome combat. It should also cook and give quality blowjobs, eh?
Except that "open world" and "well-told story" together not gonna happen even with all the joogoldz and time in the world. These things are mutually fucking exclusive. Well-told story = rails. Open world = no rails. Pick one.
