Seems like a good idea. A nice castle for all your war service with different guards or if ypur not into war a sort of gift for all your honors

hf was was cool little add on key word little hope we still have much bigger things to come

The great thing about a DLC like Hearthfire is that they can patch in new content. New house types, rooms, etc. In all honesty, I'd be surprised should they decide not to add more things to it.

in oblivion they gave us battlehorn castle

The houses you can build in Hearthfire are basically a Longhouse, much like the Jarls have in the lesser holds.

You want to live in a castle? Do the Mage college questline.

I wanted to build a sprawling castle with the towers with spiral stairs, made of stone.
