They give you guys a full game, then they ask for you to purchase some other stuff to make the game more fun. Otherwise, they can't pay the staff to actually make these games. They aren't trying to "make an extra buck" but more like "to fund another project". I wish you children would suck it up, and not complain about a Kred feature. It's not only annoying, but immature, and stupid to even argue.
