You probably haven't read secret friend of Rock Paper Shotgun Oliver Clare's review of Serious Game Global Conflict: Palestine so I'm going to link to it, as I think it's worth thinking about. In fact, I already did by the time I said I was going to. And I'm doing it again. There's no stopping me.
I haven't had a chance to play it yet, as much as a journo-em-up appeals to me (I quite like the idea of being completely out of my depth and trying to interview Hamas about how to get past the end of level three in Rainbow Islands). It's the sort of thing I wish there was more of. There's a demo here, for interested parties.
