Modding of Grand Theft Auto content, either within Grand Theft Auto games or recreated via other software, had generally performed by the player community since around the early 2000s, with one of the first major conversions being the recreation of Grand Theft Auto III's Liberty City within the Vice City engine.[116] Around 2017, Take Two began taking action against these mods, specifically issuing a cease & desist letter to the makers of OpenIV that allowed modders to alter content from Grand Theft Auto IV and V. Take-Two said at the time that its issue was not directly with the mod itself, but that it "enables recent malicious mods that allow harassment of players and interfere with the GTA Online experience for everybody", and that it was working with the OpenIV to find a amenable solution. OpenIV developers opted to remove the mod from circulation after several rounds of discussion with Take-Two.[117] Take-Two issued a statement to clarify that it would not take action against single-player mods;[118] this statement was updated in 2019 to exclude modders from including other Take-Two intellectual property or from "making new games, stories, missions, or maps".[116]
