Almost impossible to play but great just to be there.
But I walked through Hitman: Codename 47 four times and I have the right to say it's simple. It's hard to find this simple way but following it is easy. And when you don't bother about uncertain consequences of your next move you start to notice great designers' work and ominous music with latent tension. People turn their heads on you and you feel yourself as a stranger in the world of a momentary lull in the fighting. One incorrect move can activate shouting and shooting but you still have a couple of chances to hide or change your appearance. Of course it is ridiculous when Hitman puts on someone else's clothes and nobody can identify him as a tall bald killer who has been there just a minute ago. Well, it's just a game.
