I have no mouth and I must scream is one of the more original adventure games
Sound: Voice acting varies from nice to very very poor ( Dr Nazi is the champion) . Music is fantastic and gives the game 75 % of the overall atmosphere.
Gameplay: on an WIN XP machine it's hard to get this to work properly. framerate is not so good and a lot of bugs, still the story and atmosphere keep it very playable and addictiuve. I actualy finished the game in just 3 sessions. I recommend it to everyone. I found out about this on a top 10 scariest games of all time. It wasn't scary at all, it's more like a psychological game with a lot of subtleties but I am very happy I played it.
