A fast, easy to use, free, and community supported 2D game engine
Hello,
we are thinking about open sourcing our game Blood Fever (http://itunes.apple.com/app/blood-fever/id407947417?mt=8).
Has someone done something like this before and has any advice?
Some questions I have:
- What license for the code? (GPL/MIT/BSD/...)
- Can the art be distributed with the code (to allow builds and modifications if someone is interested) but not be allowed for redistribution/selling?
- Can the cocos version used be distributed with the code?
Thanks

Yes. I did it.

GPL is incompatible with Apple Developer License, basically because there is no freedom when distributing your game (because of DRM and the App Store). So use another one.
As far as cocos2D is concerned, it is under the MIT License, which basically says you can do what you want with it. Check the documentation for the exact legal terms, but you're fine with including it in an open-sourced project (or a for-sale source code project, if you take a different approach.)
For the art, etc. If it is your art, you control it. If you want to make it available, no problems. Unless you have any sort of your-use-only clause in your deal with the artist. (This is common if you've used anything from stock galleries - you usually can't redistribute their images in a re-usable format.) If this is the case, you might need to buy additional licensing for this situation.

Canabalt is just what your are looking for. They went open source but kept their artwork and other stuff propietary.

Even big houses like id Software do/did it all the time. After some years they released the full source code of their engines, you can build anything you want off of it, but you are not allowed to use their assets (textures, models, maps, sounds, etc.).
So, you may add the artwork to the repository, but disallow their redistribution. But it definitely helps the adopters when this stuff is in place so they can build the project and play with it without gazillions of problems.
