Hi. I haven't been on here for a while, but I'm back in trying to develop a game and this time I want to buy or check out a book on Unity. I find it easier for me to digest material in book form rather than reading from a screen. I also think that Unity uses C# as well so I can take book recommendations for that too. All help is appreciated.

I looked up this book earlier and it was published in 2014. Unity has had several updates by then with Unity Personal being the newest so I wanted to be sure if this would still be useful for me before I make a decision to buy or not. https://www.amazon.com/Unity-2017-Game-Development-Essentials-ebook/dp/B01K6VVBW8
