yeah about the evil Ms... this is like people saying they force RARE doing Kinect stuff... while RARE employes have said time and again that they have freedom to do what they want from MS.... and guess what if MS was the big evil forcing the studio into doing stuff they don't want... people would quite and games would suck and fail but for the most part they achieved quality in what they have been doing so far and everybody seems quite happy with what they do...
My guess is MS lets them incubate what ever they want and green light what they feel like will work well on their platforms... but nothing is imposed from the get go imo
