I have been involved with Q2A (question2answer.org) development for quite some time now and feel it has a good and big community now as an opensource project. There used to be a few alternatives http://digitizor.com/?p=8944 but Q2A seems to be the most active as of now.
I have released a few Q2A themes (latest theme) and worked on certain plugins and have helped with a bunch of Q2A installations. It scales well to increasing traffic and is easy to customize. I would like to work on this. Do let me know.
Well, this game doesn't allow that and likely never will. Their goal is to sell content packs to aspiring game designers.
If you want to make games, completely own what you make, and sell them, you should look at something like Unity3D: http://unity3d.com/
Project Spark is primarily for learning and getting your feet wet and should not be looked at as a tool for serious game developers.
