It also bears mentioning that because game mods are by definition unauthorized, they may be broken by technical updates, cause instability, or affect your game in other unforeseen ways.
Our primary focus is on protecting GTA Online against modifications that could give players an unfair advantage, disrupt gameplay, or cause griefing. This was not intentional, 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. Recent updates to GTAV PC had an unintended effect of making unplayable certain single player modifications. To be clear, the modding policy in our license has not changed and is the same as for GTAIV. We have always appreciated the creative efforts of the PC modding community and we still fondly remember the awesome zombie invasion mod and original GTA map mod for GTAIV PC among many other classics. On a positive note however you can check out how good GTA V looks at 6K. Rockstar also appears to be banning the use of single player mods in GTA V too.
We have recently covered Rockstar's new EULA changes, and the banning of GTA V players who use mods, as well as the company's statement that cosmetic mods are not a bannable offense.
