[Suzerain of Sheol]

Morrowind's easy to find online, you should be able to get it for under $20.00 is you check around, especially on Amazon. Not sure about Daggerfall and Arena, those might be tough to find, especially if you're looking for new over used.

And, Quiet, Mudcrabs are a joke in Oblivion, but the NPCs like to have random conversations about how they ran into a Mudcrab earlier today and barely escaped with their life. :p
