One thing I liked in morrowind was finding old shipwrecks and stuff in water.
So far found 2 mods for my Oblivion replay that add to the water: Alive Waters
which adds some ship wrecks, underwater plants, etc.; and Ship wrecks
. Know of any others?
Already have all my other mods. Just wanting to give my Argonian something more to do in the water. Though it has come handy in a few dungeons and a well quest so far.
