Who would buy a Walking Dead Pinball machine ?  (If it had really cool music, that would be a killer of a pinball game).

As I've mentioned before, A horror theme would sit well with me. This theme would be very successful - Zombie movies are all the rage right now. I'm not a massive fan of the genre (Zombie Holocaust), but this series is very popular. This series and Spartacus are well worth watching. Game of Thrones is also popular.
