@abstractmode @rappo I think Rappo and I have had this discussion before, or at least hinted towards it, anything that I post about modding in MP is strictly from a non-cheating, non-exploiting angle.
In fact, you can't access GTA:O with scripthook in your game. So the only files you could possibly use are ones that modify game assets or code. Some things, like parts of the weapons.xmls (I know they aren't .xmls anymore, but I can't shake the IV association) and other game code have specific network checks. Example, a bunch of my scopeless marksman rifle pictures were taken in MP, once I discovered the game didn't have an issue with the scope code, I tried something different. I tried editing how much ammunition was stored in each magazine. After multiple attempts with outrageous numbers and realistic numbers, that value refused to change in MP.
Realistically, there's not anything for R* to squawk about, from their perspective you're just a player who's got some files other's do-or-don't have! You could have missed an update or something along those lines. Or you could be a tester trying out a new update. Since you aren't doing anything malicious, flags shouldn't be thrown.
GTA:O is a great system and the future of the GTA series. However, R* has an obligation to maintain the status quo and insure their service is secure. It's their multi-million dollar baby, not ours. Having said that, I think that file editing in GTA:O is a much safer alternative to the MultiVs and FiveMs out there. (PERSONAL OPINION TIME LOOK AWAY IF YOU DON'T LIKE THAT SORT OF THING)
Quite frankly I see the future of MultiV, FiveM, and all the others ending the same way. Rappo getting a DMCA from T2/R*, the mod authors getting PIs sent to their door with cease and desist letters, and the cycle starting all over again.
In a perfect world we could all have our way, but sadly I don't see it happening. R* would never sanction a cd-key checking GTA:O alternate and they certainly wouldn't sanction a non cd-key checking alternate. They are invested in this current system and I fail to see them deviating from it.
