So, assuming they make an actual RPG from this license, is the setting interesting ? What kind of RPG would it lend itself to best, openworld NV-like, or PoE like ?
It's a bit of a kitchen sink setting, with room for any kind of adventure really. There's areas that are perfect for horror games, or barbarians fighting robots from space, or pirate adventures, or holy warriors fighting a massive and world threatening demonic incursion. Of course, there's more 'standard' fantasy countries too.
It'd lend itself perfectly to PoE like game, I reckon. If they did something like that, I'd love to see Pathfinder's module format get copied over to the game, so we get big new adventures in different areas of the world on a regular basis.
