playing in the game industry 
The chapter on the Swedish game industry gives an interesting insight into the success story. Its final focus on the collaborative business culture as a distinctive feature is particularly thought-provoking and indeed raises some questions, e.g will the shift to transnational cooperations erode the collaborative spirit, or people with a more hierarchical and competitive background will notice even more opportunities this approach can make available and consequently, adopt it to a greater extent.
Could you write more about the additional publications on strategy? When are they going to be published and what are they going to focus on exactly?
