YES THIS GAME IS FINE FOR TEENAGERS! Geez, this site is more uptight than my great grandmother! This game is loads of fun. I have the PC version...its a fighting 3rd person action game where you have to puzzle and fight your way through obstacles to reach the demons. You are a demon fighter, fighting to protect people and particularly, the girl you love. All of the characters have wonderfully puffed up heads, a lot of ego, and arrogance that makes the dialogue adorably unrealistic but fun. It is set it a beautifully constructed gothic world and there is little blood involved at all, the only thing you kill is demons, and the demons are basically stitched together monsters that attack you.
The only problem perhaps is the sexual undertones of one minor character, who is a woman warrior that dresses promiscuously and dates a main character, Dante. But the main girl who Nero, the main character, is trying to save, is a very unusual woman love interest. She is a member of the church within the game (not the same religion as christianity, but supposed to appear similar) dresses very modestly, doesn't have large breasts or butt, is actually not particularly gorgeous but just pretty, like most young women you might meet. She keeps her hair tied back in an uptight, modest way as well, and is very quiet, sheltered, and kind. Honestly, I applaud this game for her; this is the first game I've ever played that was obviously designed with a lot of testosterone that had a female character as modest as her for a love interest. And Nero loves her very sweetly and innocently, in a way that is almost funny in contrast to the rest of the games swagger and hilariously male bravado. It isn't meant to be taken dead seriously, and I didn't. The characters are lovable because of their arrogance and yet good sense of humor and heroism. A great game.
