Advertisement in XNA windows games (not Windows Phone 7)

What existing services/libraries are there for in-game advertisement that开发者_JAVA百科 can be used in your XNA games on Windows?

If you are looking to advertise in xbox360 then you are out of luck. You will have to manually do this, in a way that will still allow to pass peer review (subtly).

And even so, it's not like a user can click the ad, so how would the ad place know how much to charge you?

I have decided to rely on donations outside of the Xbox 360 and use the XLIG for distributing on the xbox 360.
