Here you can see one of the first games to be shown on the new windows 7 phone this week at the MIX10 conference in Las Vegas.
Harvest is the name and cross platform play is the game. As you can see from the trailer users can seamlessly have their XBL account active on the mobile and even unlock achievments whilst on the go. Then carry on with the game on the big screen when they are back in the comfort of their favourite butt groove on their sofa.
This could bring a whole new dimension to achievement whoring!
