Divine Divinity was released the 2nd of august 2002 in Germany and a few weeks later in the other countries.
I think Larian took about 3 years (maybe more) for the devlopment of the game (about 1999 to 2002).
The stone in the treasure cave is just for remembering the bad events and the victims of the 11th september 2001 in the USA.
The easter egg area just looks like the Larian office in Belgium except Lynn who is much pretty in the real life than in the game. <img src="/ubbthreads/images/graemlins/shhh.gif" alt="" />
