Did you ever try any mods on Oblivion?

I've got a few, including a really interesting one(forgot it's name tho) where you can be the owner of a castle, by just defeating the people who attacked it. I think even skyrim should have something like this, I know they have the king system mod where you can become a king 😃

I did try only a few that gave some extra quests but not too many. I never saw that they have the castle mod system, can you give me a link to it so I can try it out until TES VI comes out. I have time to test all the mods.
