On the easy difficulty level it’s not too intense, and you can save anywhere so you can definitely come at it in small bursts of time. Some days I have 3 hours to play, sometimes 10 minutes. It’s always a good time.
I’m not so sure how appropriate it is for a 14 year old, though. There’s a lot of brutal violence, macabre imagery, and sexual content that is questionable for a young teen.
I’d do a little more research into whether you’re sure it’s age appropriate, but on all other counts I’d say it’s a winner.
