Hm. I need to think more to add sth to my post later but I guess that ending of Another World will be one of this time I was truly affected by a story of a game. And whole story of the Blade Runner game - so true to the book and the movie, so true to a player - you actually have influence of what will happen at the end of the game. This is not only adventure game for me – You actually role play McCoy in that peace of art! Because you actually can decide about what will happen with almost all of the characters (including you) you can really attach yourself to them. And that's what I call a true virtual world.
For me Blade Runner is one of the best game ever created and I am disappointed that there is no more games like that.
