So skill progression is in fact gained by use of a specific skill and not some other system where skill points might be given and allocated by the player?
I am a huge fan of Oblivion, so I would be very excited by this kind of system. One of the things I noticed is the the makers of this game gave up on pure use of skills for balancing and allow characters to purchase skill points from NPC trainers. Particularly, skills that characters would use a lot, like restoration and destruction magics, were much harder to advance in then say illusion or conjuration.
By the way, I will pay $60 if you port the game over to the Xbox360 platform
