Just finished it and it blew me away completely. Haven't seen all the endings yet, but SpoilerI went with mankind is incapable of using technology responsibly and picked the Darrow one. And I must say, I liked it. Even though I know some people tend to dislike it, I think it fitted the game perfectly; Spoileryou're just a pawn, and nothing you do will change the world.

Anyway, in short: it's the deepest, most detailed and challenging game I have played in a long long time and I will plunge back in straight away.

Edit: SpoilerI hate Megan now. Do you?
