Hello, tony! before I say anything, I want to say i am not a part of the team, so this is just a fan answering your question.
The site says it's a trilogy, but by reading
this, and countless posts and threads on the forum, and
this, you will find it was meant to be 3 games, but now, due to vivindi, and a bunch of legal junk, it's only the 1st 2 chapters. This is all I really know. I could give you countless links to posts on the forum about it if you want.
thanks,
atec123!)
