One thing I have ALWAYS hoped for is that Bethesda will let us create our own realm...similar to how Mankar Camoran created his
Not only will it be a nice way to try out the creation engine construction set, but it is far more immersive and engaging than just having a Manor to store your inventory items
You do understand that the Creation Kit isn't just something you pick up and play around with until you get what you want, right? It's pretty close to a professional game making tool, and part of what Bethesda used to make the actual game. It takes a lot of practice and patience to learn to do what you're talking about.
So obviously you can do what you're asking, but you truly have to learn how to mod (model, texture, script, etc.) before you can make it. Bethesda aren't just going to have something set up to where you can easily create your own realm of Oblivion.
