That would be Awsome!
You can pretend you're god himself.
I can't wait for the next serie of the game.
ES4 Oblivion has allmost all the things you'd want in a RPG and if they add even more I wouldnt be surprised if it's the next hit in video games.
I personally would like spells to make you ether very tall to smash buildings and stuff!
That would rule!
But the thing that would probably stop the game designers from adding such extras is probably stucture regeneration.
