Firstly, let me tell you what Painkiller game isn't about. It is not about pretensions, it is not about ambition, it is not about cliches. It is not about "complex environment" or unscripted AI. It is not about main missions, sub-missions and sub-sub-missions. It is not about "revolutionary graphics", "revolutionary game play" or revolutionary anything. And it is definitely not about the sells and the end-of-the-year figures.
It is all about the fun - plain and simple.
It is about atmosphere, it is about art, it is about immersion. It is ultimately about people having fun making it, so that other people can have fun playing it. Painkiller reminds me of the good 'ol days when games were made to be played, not only to be sold.
Now...You go back to play Crysis. And I am going to replay Barracks - that masterpiece Painkiller level. Wanna bet who will have more fun?
