In part I agree with you, DesVoux. But I already create and change whatever I want when I plan a game. But I'd like to read a little more of official material to give me ideas.
In my games, usually AIs are a lot more mysterious and rare that I see them in RAW material, but I like reading the references of they as being not so scarce to give me some ideas. The same with Amazonia. My view of it is quite different from the official one, but I'd like to know more about the official one, as most of the time, even when I don't want to use the source material, it has a nice research job on it.
And it's a little difficult to plan campaigns here, since, as you said, megacorps presence is not as intense.
