Pour confirmer ce que dit _coo_snake, je vous passe le lien:
Regardez à la fin du premier post
"After the demo Todd confirms several things about the game
They're aiming to have mod tools out at launch
There are dungeons inside glaciers
Athletics and Acrobatics are gone
There are kids, but you cant kill them
Horses are not a definite inclusion
Levitation is not included
The ability to buy houses will return
At least 5 full cities.
And that's about it, ENJOY! "
