just wanted to login to say i support this thread. because i like the idea that if your ill prepared to venture into a dark place you need to take another route that immersion gets killed if every dungeon thats supposed to be dark is just bright. in the case of Underdark there is a choice of going through Underdark or going through main road. If it works the way that you need to be prepared with torch or darkvision if you choose to go through underdark then that is up to you to be prepared for that. anyways nice comparisons i support the notion.
