Has anyone looked at mining a codebase like this before? Is it possible to extract useful parts for your own work, or is the codebase usually pretty tightly coupled, and/or inscrutable?
If nothing else, it'll be amazingly useful to make a similar/adapted work from it.
I remember a good while ago, there was another game company working on a military vehicle game that went belly-up and released their source code. I was able to use one of their OpenGL libraries for a side project of mine and it came in handy. It was actually just rewarding to use it as a reference when there was so little well-performing example code out back then.
My experience with game development shops is that they often have a vision of making engines/tools that they can reuse for other games or the sequel. So there's a good chance there are at least a few libraries (especially closer to the user or to the hardware) that will be reusable.
