Personally i keep my "wishlist" hidden for now, thats more something for after this game when i have an idea of the games style and where the story stands etc.
Now its way too early for many wishes and hopes since there is no clear idea how the developers have evolved from origins.
After this game is revealed however, boy do i have a long list of things i would like to see.
But the one wish i can say now, is that i hope with court of owls more than likely being in this...i would love to see the focus being on Gotham city more.
I want on every corner history and easter eggs...arkham city times 20.
Make gotham a character on its own since we will spend a lot of time in parts of the city probably.
I want the city to drip with history and charm, being filled with unique buildings that tell us how gotham became what it is and so on.
Other than that, i dont have anything i currently want...at least till after the reveal on saturday.
