I think Stern knows you guys want code. The problem is you buy the games anyway. Simple as that.
The Video Game buying public on reddit have been having similar problems with incomplete games being released, and they have started a NO PRE-ORDERS IN 2015 campaign. That might be more useful. Games that are already out we have no influence over. But if you refuse to pre-order games until you can check out the code, you can incentivize the developer to turn out more complete work.
