Scotland Yard... Junior?

I found this at the local toy shop. You know of Scotland Yard, my favourite board game of all time. I didn't know there was a Junior version of it. I can only imagine how watered down it is from the original, but Mr X sure does not look as mysterious or scary on the box. I might buy it for Wolfie, as he is getting into board games, but I still want to get the real thing.
