I have a very basic question about precursors. What is you development model with regards to GPL and open source. Are you going to just use Crystal Space as a engine and have everything else copyrighted?
If so I think you are making a mistake as a game of this size a complexity will prove nearly impossible to create with the resources you have. Many people have tried this before and failed. There are middle options that I think would serve you better. Go check out the PlaneShift licence (
http://www.planeshift.it/pslicense.html ). While this may not suit you, if you are realistic you should realise that to achieve the precursor universe you will need all the help you can get. and the more restrictive you copyright the less help you will get.
I personally think that plane-shift have the right idea. By keeping copyright of all the content but making the code GPL. This has many advantages, and few disadvantages. The question is what are you gaols. Do you want to create the greatest space game ever, or are you trying to create a game development company?
To make my position clear, If I manage to create a good solar system generator I plan to make it GPL. So that I can use all the open source resources that can help me and also so as many other people can benefit from it as possible. It would also allow other people to easily contribute to it as well.
As a suggestion I would suggest that you make precursors a Non-Profit entity, with open source code and copyrighted content. The aim being to create a game for a community with a commitment to making it the best game ever while charging very little with all moneys generated being invested back into the game ( to cover equipment, wages for staff and developers ect.), this would also allow a community to form and support the game. Also it would give the game a long term survivability. I believe that most of the precursor team is currently in collage, when you finish your studies you will find it very difficult to give the time necessary to complete a project like this.
There are literally hundreds of people who will contribute to a project like this if it is setup correctly. I suggest that a lot of though should be given to these issues.
