Have you seen the Game Programming Patterns book (http://gameprogrammingpatterns.com/). It was originally a blog that later become a book, and I think you can browse most of the content online. It's full of interesting lessons and patterns and deals with coupling and state management. It won't have the answers to copy and paste, but it gives you a lot of food for thought and it's really well written.

I'm not a game programmer by trade, but I'm interested in that stuff and I really enjoyed it all the same. It made me rethink some stuff about enterprise patterns too.
