I do my business plan with software wizard and I have gotten to the section named "Market Analysis". I have to describe the different groups of target customers included in my market analysis and explain why I am selecting these as targets. And I think it would be good idea also to summarize market growth. Where can I find some facts about game market and game market services (b2b services such as 3d modeling, animation, cut scenes production, etc.)? I would like to get links to free resources and not-free resources. Thanks you.

The ESA is the main industry trade group for US video game makers. www.theesa.com has alot of *general* stats related to the game market. Stats like overall sales, sales of pc/console/mobile games, units shipped, year over year growth rates, and demographic information.

The ESA gets their data from NPD group which compiles the data. NPD is a pay-for service and nothing they sell is cheap (not as far as i've been able to tell anyways). The ESA site has alot of good data -- for free even -- if you are willing to dig through their press releases.

As far as the more specific B2B stuff you are looking for i'm not sure where to point you.

Good luck!
