Nope! FiveM does not interact with the Rockstar Online Services other than to validate your game copy the first time you launch it. This validation emulates the game's interaction, and can not be detected by Rockstar.FiveM also doesn't modify your game files at all, even when downloading server assets, so you don't have to do anything to switch between FiveM and GTA:O.

We need to do this to check if you actually own GTA V, when our automatic validation fails. This data will only be sent to the Rockstar Social Club services, and is not transmitted to us, or any other party.

Unfortunately, offering FiveM on any game consoles is not feasible, since FiveM uses advanced interoperability mechanisms only available on the PC platform. Furthermore, FiveM relies on the PC platform being open to developers without requiring any approval from the platform owner.

No, all your existing scripts will still work with the game when OneSync is released, with minor changes to support higher player counts. Of course, OneSync will enable new, better ways of doing certain things you do in your scripts, so you might want to take advantage of those when they're released.

Modifications, not multiplayer. FiveM provides both a singleplayer as multiplayer experience. This allows players to use our features in singleplayer as well.
