This is the book I'm referring to; I'm not sure if this is by the company/website you're referring to. I usually think books on video games are bad but I thought this one was decent enough as I didn't want to immediately get rid of it after reading it like usual.
I will say (again, I know I'm in the wrong place) but as a fan of WA2 I am pleased that it has gained somewhat of a legacy for it's story and themes these days. Yes, I know the game was outdated back when it came out, got it, but I still loved it. Still, I don't agree with this book in saying WA3 was peak WA. Just, no.
