To DrTeatime: I'll try to be clear with this argument...

I heard somewhere that simply changing a game file (in the folder of that game on the computer, I mean) is considered piracy, because you're "modifying a game without permission", even if you got the game itself with your money - it's an idiotic thing I read somewhere in the Internet. Even cracking a game to avoid using its CD everytime you want to play it is considered piracy, too.

I did with GTA IV, changed models and vehicle driving settings, and a game I own/bought is a game I can modify freely.
