What other SIGs do you think the GA SIG could benefit from working with?

In what ways should we work together? What are our mutual goals?

Easy: ask the Design SIG if they can support a high quality overview about game elements.
With structure of point of view of game designers and game developers.

When we have this we could describe recommendation how to avoid barriers for each element. (Of course we need also a general part).

I think the design SIG would be great to work with. I may just send them an email.

Do we not need an idea and a concept about the cooperation?

The first email will likely be seeing if there is interest, seeing where we overlap, and discussing ideas on how we can work together. Once we know their goals, we can see our how goals coincide, and work together to formulate a plan. That way it is much more of a group effect then a "You designers should do accessibility in your designs because it's good for us" kind of things.

You could also ask more friendly :-)
