This may be a stupid question, and I'm not sure how active people are on this board any more, but I figured this would be a good place to get possible answers.
The tileset has two different sorts of barriers (not including water) - a brown one and a green one. I've always assumed that the brown were mountains and the green were thick forests. Neither would prevent a determined individual from passing in the real world, but they work as barriers for PS3's "lots and lots of walking" play-style.
The area I'm thinking about specifically is the Divisia region. In the game, the only way to pass from the dome's northeast quadrant to the entirety of the rest is to go through the castle and the dungeon. I doubt that the nobility is keen on every merchant and pauper who wants to cross over traipsing through their courtyard, so I imagine there must be some other way through; probably various paths through the forest or a mountain pass.
What are people's thoughts on this?
