It is a fair response guys.
But what I loved in Demon's Souls was the world tendencies that changed the world/fell and even gameplay... and how the PvP and Coop worked.
There is no way to these things worked well if you made a open-world interconnected game... you need to have different worlds separated to have different tendencies to each other.
And there is nothing confuse...
1) Die and the world goes 1 level black
2) Beat it and the world goes 1 level white
* Beat defecting the boss (the first time only) and the world goes full white level.
* Killing red phantons make the world goes 1 or 3 level white too (I don't remember).
