The IGDA’s Casual Games SIG has just released 2005 Casual Games White Paper (2MB, 125 page pdf).

The White Paper is the work of over 30 volunteers in the casual games space, and the list of contributors reads almost like a who’s who of the industry including; AOL, TryMedia, Skunk Studios, Large Animal, Pogo, Shockwave, Garage Games and many others. One of the most interesting sections for developers may be the Games to Market section which asks the same questions of 18 different publishers and gets answers about a variety of topics including Commission Breakdown (50-65% rev share from Garage Games) and even who/how to contact each company.
