The Hobbit was just about the first Computer Game I ever owned (Commodore 64). Everyone my age has read the books or knows the story. So the decision to go with "The Hobbit" makes sense. You get the older generation, the kids and also the movie goers. Good Strategy - and not too late.
We REALLY need a theme aimed at the collector base. A horror or Sci Fi theme. Prometheus would have been an awesome title.
But I can understand JJP wants to reach as many customers as possible to build up the cash and reputation. Hence WOZ and Hobbit.
