Open access for XBOX Live achievements
Give ability to create games that have access for xbox live achievements. It doesn't have to be full access. Still only partners can have a "Xbox live" mark on their game icon, but having a one place for achievements, leader boards and friends would be great (WP7 Live?)

Actually, if the Xbox team wants out of this, it is fine, but Windows Phone Games still !need a concept! for having an achievement system, that is nice and stable.
@Tim: There should be open access to achievements, but without the points. This keeps the points valuable, but the user experience the same across all games.
I disagree, keep achievements restricted. I like the fact that there's a sense of quality control around what can give you an achievement. It makes the achievement points actually mean more. Otherwise you end up with a load of free games of really really cheap games that are designed just to give you achievement points. Then peoples achievement score becomes less about achievements for playing games and more about who's spent time downloading rubbish just for the points.
