Wow, this is an interesting question! 
I think our level of involvement is probably somewhat unique. Ironclad owns the IP for Sins of a Solar Empire and they have control over what goes into the game (or doesn't). However, we've been testing and playing Sins since we signed it, making suggestions on how to flesh out/improve things, etc. We're also assisting Ironclad with the creation of the in-game movies for Sins, writing the manual, and other elements that developers would usually handle. In the same vein, we're giving Ironclad a great deal of input over various aspects of the marketing that developers typically have little say in - and this has worked out extremely well (I think our two companies complement one another amazingly well).
