I made a real push to finish Professional Techniques for Video Game Writing tonight. I started reading it a few days ago. While I did persevere, I quickly did realize that it's a bit more advanced than where I'm at. I'm going to need to go and read some of the other books on game writing that I have (which are more basic) before possibly re-reviewing this one. But I am really glad that I read it. I now have a lot more knowledge and insight into video game writing than I had before.
Professional Techniques for Video Game Writing is a book full of articles written by actual game writers. It covers a whole range of topics, from writing game manuals and tutorials to writing for all audiences and for new intellectual properties. I read it from cover to cover, but it's the kind of book you can easily peruse, reading the chapters that pertain to you. Reading the whole book all at once is a bit overwhelming, especially when you are new to game writing. But this is definitely a good book to digest in smaller chunks.
Oh, and my favourite chapter was by Andrew S. Walsh on Writing Tutorials. It was funny and super informative!
