Right, this grid is only a suggestion, as it might just end up confusing you, it's just that quite often, the exam question asks you to apply your understanding of certain concepts (synergy, media convergence etc.) to certain stages of the production model (developer to consumer).
So part the challenge in G322 is not just retaining the information about GTA4 or Red Dead but organising in a way so you can talk about the relevant bits of the case study in the exam.
Use this grid after looking at this post here for GTA 4, or completing the Red Dead Prezi and worksheets.
