Halo would be a tremendous theme. No doubt about that.
But...here it comes.........might be too much of a theme for a pinball. Yep, that's my opinion. There is so much "another world" and intricacies to a console game like that the pin would be a let down for a serious gamer. At least it would for me....again, this is my opinion.
Not to be a downer, just don't see a strong, lasting, successful pin with a franchise like that.
flame suit on!
