this is a general suggestion to fix a major flaw i saw in OB. Morrowind not so much.
Caves.
Why are there doors on cave entrances?
Why are caves in the middle of a flat forested area instead of a more logical area?
Why are all the caves inside of boulders?
Why do they look like stony glowing mazes?
i know a bit of the reasoning - bugs+time restraints
I have a few suggestions
one-if you have to go through a loading screen into a cave then make the entrance of the cave NOT A DOOR,
make it convincing- like the entrance to an oblivion gate only instead of fire it is a black void.
two- make the exterior area of the cave more convincing. like where a cave SHOULD BE...not in the middle of nowhere. rocky watery etc.
three- make the interior more cavernous, take example from SURE-AI's NEHRIM mod. which creates an amazingly REAL feel to the dungeons and caverns.
create skill based movement throughout the cave in order to traverse it faster and safer- skills involved would be mostly acrobatics and athletics-possible future survival based skills.
four- REMOVE AMBIENT LIGHTING!
i dont want my caves looking like a glowworms toilet--unless they are glowworm toilets!
any other thoughts.
