Corporate strategy changed 5 times in the 1.5 years that I was with Glu. Change is not equivalent to leadership, unfortunately.
User Acquisition strategy remains firmly in a Mobile 1.0 mindset.
Brain Trust reviews (a Pixar approach to in-house evaluation) do not scale well to mobile development.
I saw significant pettiness when projects were "peer-reviewed" across studios. This includes the responses I saw from our own studio when we reviewed games developed by other teams. None of that was healthy.
We did not have enough mobile game players among the mobile game makers. Therefore, there was a limited real understanding of the market direction and our audience's expectations.
I experienced a general unwillingness of upper and executive management to execute on tough personnel decisions until it was too late.
