The issue is ... what the seller can offer for more price.
You make the game more expensive, great. But does it offer better infrastructure? In this case, no.
There are games that just to register you need to place the data of your credit card, but they are great games! With animations in 3D, characters that seem real, with film situations ....
But even when you can squeeze the pocket of a supermechs player? What do you offer in return?
