Somehow a new Death Star around a different forest moon feels more or a retread than returning to the one we already know to have existed.
Geonosis is Tatooine Red and it appears in the same film as Tatooine Orange but doesn't feel any more exotic.
In terms of story it makes more sense to me if Geonosis and Tatooine were the same planet too.
It leaves room for more exotic places in my mind that one world of desert.
