Hush hush, industry secret here... Lionhead's Tools team use C# now for everything, and basically want people to move over to XNA!
As in, the people making Fable 2.
There was an interview with Peter Molyneux in Develop (a British games development magazine) where he raved about XNA.
My view of it is that it is perfect, for me, but way, way,
way worse than DBPro/Blitz/Gamemaker for first timers.
I think the confusion (and I think this confusion is among Microsoft as well), is whether they are aiming at indie games developers (as in amateurs, probably teenagers) or
indie games developers as in, professional games developers who aren't signed with a studio.
I think it is the latter.
If you don't know C (or a variant) going into it, it won't be much help.
It will, however, make it possible for say, 4 friends who work at EA to break off for a year and see if they can make it on their own.
@Jeku
But what actually connection is there between the two? Does 360 come with a USB cable, or is it over the internet?
