Dark times have fallen upon the GTA modding community. Popular GTA mod OpenIV has received the axe from Rockstar lawyers after the powers-that-be issued a cease-and-desist letter. OpenIV has nearly seen tenure in the GTA community, but the ban hammer finally came down on the software. OpenIV, according to the letter, allowed "third parties to defeat security features of its software and modify that software in violation of Take-Two's rights."
The devs agreed to stop the distribution for the software. However, Rockstar previously stated "No one has been banned for using single-player modifications, and you should not worry about being banned or being relegated to the cheater pool just for using single player PC mods."
We're a little baffled by the stance. PC modding has been a staple for gameplay ever since Doom .WAD files where you could change zombies into lurking purple dinosaurs. Unfortunately for the modding community, GTA seems to be getting the hose when it comes to exploring more functionality. This might give advantages (read: sales) for Bethesda and their games like The Elder Scrolls and Fallout, which are heavily modded in the gaming community.
