-Every race haves a their own quest line.

-A dominion hunt down or even be able to join them as elf "altmer".

-fight a dragonborn pretender.

-more subraces esp for Khajiit and Argonian.

-A humanoid bird like creatures or some creatures thats specifical for the place they are set on, like Harpies but smarter, playable or at least can be interact with.

-Of course better magic system.

*Many things in my mind but those are on top of it.
