Painkiller and one of its expansion packs -the original not the one with the half-devil main character- and I have to say that I find the starting Orphanage level more disturbing than all of Doom III and its expansion, or any other game I can remember for that matter. I thought it would be more like Jericho, fighting demonic enemies and twisted versions of the past, but so far it's not been like that at all. Maybe things will change when I get further into the games -I'm playing both- but, at the moment, one is an ok shooter and the other is simply troubling. I think it's due to the fact that you, the player, are forced to kill children -even if they are zombie-like demons, they still look and sound like children-, and there's no way around that fact. In other game, like Fallout I/II, the option was there but you were not forced to take it if you did not want to - there is no such freedom here. Maybe it will feel different once the initial shock wears off -I was not expecting this and so it probably had more of an effect that it normally would have-, I'll see and post what happens as I get further into the game.
