Okay - on the topic of morality.
I must agree with Dom Pedro II, as long as you give credit there's no real harm in it. Plus, it's not like we're causing people to not buy these other products, and we're also not trying to sell these graphics.
Further, about the whole starving people. It is a game - so i guess if you have a problem with changing 1's into 0's then maybe you should be all riled up. Realize that when you starve somebody in say, New York, that you didn't actually starve a real person in New York, it's just a game.
