Quoted from jawjaw:
My big criticism is why is it so hard to add callouts and video assets? Most modern games seem to have a limited set with the same callouts over and over. With modern hardware, I would think it would be easy to have thousands of callouts and full library of video assets if theme is based on movie or tv show. It would be cool to hear unique callouts every time you play the game or even seasonal ones.
One word answer - COST
Of course it's easy to add almost anything you want with modern technology BUT callouts made by (as one example) one band member, can cost up to $100 PER CALLOUT and PER MACHINE!!!!
Most people have zero clue about how restrictive many licences are, they usually have dozens of things you can't do or use, mostly for their own reasons.
