I have to say this is one of the best games I have ever seen ever. There is an amazing story line, brilliant characters, it's just a fantastic game. There is some language I wouldn't use in a normal conversation, but not a lot of it. I watched a play through on YouTube, and the commentator swore more than the game. There is some mention of sex related topics, but you never see any nudity. There is frequent mention of gathering for whiskey and cigars by the City Watch, but no one actually drinks or has a cigar. It has the positive message that war is not always the answer and that sometimes it's better to get in and out like a ghost. I do have to say, the game is MUCH better if you put in the time to do every side quest, and get every rune and bone charm, because some of the quests you go on to get them give you character info, or can present you with another way to reach your goal non-lethally. All in all, the best game ever.
