I have mixed feelings regarding having a persistent worlds in roguelike games. What I like about it is that you can actually bind yourself to that world, meaning that you can continuously explore it by each time you are born in it, allowing yourself to memorize and feel familiar with it. I also like to witness your last actions from previous characters unfold, to build consequences at the world's present time.
This is all nice but also feels like exploiting. When you die exploring a certain area you will unconsciously carry this knowledge to your next character, i. e. this will let the player prepare his next character accordingly to that specific area containing a specific type of danger that could only be dealt in a specific way.
This could be solved by terraforming a new world each time the player creates a character so that the player feels the world as new as we once felt Earth in our real lives but I really don't know how people would think about this. Maybe I should let the player choose if he wants to reincarnate in the same planet?
What do you think of this?
