>>44955266You can have linear progression (Go from Town A, through dungeon A, to Town B) while still having a world to explore. You could put an additional, optional dungeon to explore before A, have areas in Dungeon A that are just for exploration like the old Pokemon games, have an optional village to visit, etc, etc.
What we have in Pokemon now is indeed go from Town A to Town B by way of Dungeon A, but it's just a straight hallway with no diversions. And the one "diversion" we do get is just a big open space with nothing in it, nothing to explore or anything.
