We had indicated on the mobile design resources page that we would be adding design recommendations and style guide information. This information would be recommendations that don’t constitute a design pattern, but nevertheless are good or best practices. And of course, the information is free and you are encouraged to add or edit content.
We just loaded a long page on mobile game design. It’s the chapter on game design from my 2003 User Interface Guidelines for J2ME MIDP 2.

We’re still working on getting other major information providers (a quick call-out to dotMobi, W3C, Nokia, SonyEricsson, Sprint, Vodafone, and others) to provide support and/or information. If you provide support in the form of a lot of content and/or money to defray our expenses, you’ll get your logo built into the templates.
Wow, thanks for posting this! It’s very relevant to my online mobile gaming project, wifight. Great reading!
