Looks like a good varied bundle with lots of options for game development.
Just a note on the Unity book - it deals with 'UnityScript' and calls it 'Unity's Javascript', but just to call out that it's very much a language specific to Unity, and for that reason most people use C# with Unity because it's the standard C# implementation so can be used outside of Unity too.

I imagine there might be some appeal to that, especially if your server is running NodeJS.
