NASAGA conference - North American Simulation and Games Association
The "North American Simulation and Games Association" (NASAGA) is having their annual conference October 5-8 in Manchester, NH, USA.
This group is mostly made up of people who use simulations and games as instructional tools. This is one of my favorite conferences.
Disclaimer: I'm a board member, and I'll be co-leading a pre-conference workshop ("Rapid Game Remodeling", with Les Lauber). But those are true because I find this organization so fun:)
