All i can think is why change it from Divine Divinity to Divinity 2?
Divine Divinity was originally called Divinity: Sword of Lies, but the publisher changed the name to the slightly repetitive name it is now known by. If people have any opinion of the name, I think it is generally considered to be somewhere between a bit silly to just dumb (made a couple 'worst name' lists for games), and a lot of the reviewer I recall seeing started off with a comment on the name.
It has to have a reason? You are not Divine anymore
Well the main character is no longer the Divine One, anyway.
