"It occurred to me, immersed in my 50th hour of Just Cause 2, how far beyond that silent audience, proscenium arch, here's some well-paid 'actor' pretending to be someone else experience we'd gone and how very timidly other forms of storytelling entertainment had reacted to the challenge of the beast in their midst" - Grant Morrison, interviewed here. Someone needs to get that man some story games.

With one more session played and some time to think about it, I think I've got enough ideas for a review of sorts.
