So I have a ps3 which means bethesda hates me for some reason and won't give me battlemore castle which btw is like my dream home for oblivion so I was wondering if theres anything in oblivion that would make a reasonable substitute.

No, Bethesda doesn't hate you, there is a reason why PS3 Got no smaller DLC, It came out a year after the Xbox 360 version and by then it was pretty much a dead project, And no, the best home you can get is the Skingrad one, It has display cases, you can get a maid, you have 3 floors and a basemant and lots of storage.

Skingrads to small for me maybe if I kill a count I can have there castle
