Rex Brynen and Gary Milante recently started PaxSims, a great new blog, "devoted to the development and implementation of peace and conflict simulations for education and training purposes." It's well worth checking out, and they are posting frequently.
Their most recent post is on a new article in Joint Forces Quarterly on the National Strategic Gaming Center at NDU. There's some great stuff about a new initiative by the NSGC to get the various gaming shops to engage more with each other and with the broader policy community with regards to gaming methodology. I wrote about a previous JFQ article on the NSGC here.
