Rockstar writes down its mod rules two months before GTA 6

Rockstar Games has put a Mod Guidelines page on its own site, dated 10 September, and it is the first single document in which the studio spells out what players may and may not do with the code, maps and assets of its games. Almost nobody noticed it until this weekend, when the link went round the modding community and the gaming press.

Four bans sit under the heading "Respect Our Games". Mods must not expand or modify Rockstar's official storylines, plots, missions, characters "or other elements of our established continuity". They must not mix maps, locations, characters, storylines or in-game assets from one Rockstar title into another. Multiplayer modding is allowed only on the "official licensed Creator Platform", which is FiveM, or under a licence granted by Rockstar directly. And nobody may rebuild a Rockstar game "to operate on consoles, hardware devices, or other platforms where they have not been officially released". GTA BOOM reads that last line as the end of fan ports such as the Grand Theft Auto V build the community got running on Nintendo Switch.

Money gets its own section. The Creator Platform is called "the exclusive licensed home for our community to monetize their mods", and everything outside it "must be strictly non-commercial". That continues a line Rockstar has been drawing since it bought Cfx.re, the FiveM team, in 2023: in January the paid Cfx Marketplace opened, and in February the rival platform alt:V announced its own shutdown at Take-Two's request, writing that "Rockstar Games and Take-Two Interactive have made it clear that FiveM is the only authorized platform for GTAV multiplayer modding". The same section bans real-money gambling, loot boxes and gacha mechanics, the selling of in-game currency for real money, and cryptocurrency in every form the page can think of: NFTs, tokens, memecoins, stablecoins. Advertising, product placement and sponsored content inside mods are out as well.

The intellectual property section closes off cheat menus that interfere with official online services, the use of Rockstar logos to hint that a mod is endorsed by the studio, and anyone else's protected work: art, music, photos, brands, logos. Two lines are written with generative tools in view. Modders may not modify or reuse voiceover performances from any Rockstar game, and may not use a real person's voice, image or likeness without written permission.

Grand Theft Auto VI is never named. The page covers "the Grand Theft Auto and Red Dead Redemption series, and other titles", and today the rules bite in GTA 5, where the roleplay scene actually lives. The timing is what points forward. GTA 6 arrives on 19 November on PlayStation 5 and Xbox Series X|S, consoles where classic modding is impossible, and Rockstar has announced neither a PC version nor mod tools for one. Whenever PC modders do get there, this is the rulebook they start from, closing line included: Rockstar "reserves the right to take down any mod or other user generated content at any time for any reason".
