Wow reading over the comments here, I thought saying that they never would have paid for it anyway would be the dumbest thing I read here, but the comments that the system requirements were too high so people pirated the game really takes the cake. Seeing a game dev here make that same point is fucking hilarious and sad (I am not going to point out who it was or which post it is).
There was a fucking demo. The demo was enough of an indication that the game would or would not run on your PC. Pirating the game to see how it ran on your system is stealing. Pirating the game because you never intended to pay for it in the first place is stealing. You are using something that you have no right to use, just like pirating music, movies, whatever. You can claim that you never would have paid to see a movie so you downloaded it, but that point is completely VALUELESS. If you think that makes sense, you are a moron.
If you never would have paid in the first place, you never should have downloaded it. Because you did, you had a desire to check it out and I am sorry, but that costs money. If there is no free demo, you don't get to play it for free. Seeing people make these stupid arguments here and then complain about GTA being a console-exclusive for now is pathetic and sad and more than a little dumb.
