ok.

can conitec handle the complete microsoft policy?
(some xbox-menu-interface features, achievements etc.)

is there a manual with rules to do prepare the source and interface-design for use 3dgs scripts @ xbox?

i know some rules like "place a 'back to dashboard'-button at main menu. Make a 'press start'-startscreen" etc.
i talk about advanced things like community functionalities etc.

Consist the port a C# project with use of XDK? Otherwise i use unreal engine or unity (at last..) -> are commercial approved @ gaming consoles.

edit: by the way.. there are already xbox 3dgs games out?
