Why GTA's RP is something rn ?

[RughCuttle]

GTA and Roleplay isn't something new. I think even in singleplayer, after modding was a thing, people who like GTA use it's assets (the game) for world building and RP. I played MTA's text RP for a tiny bit (most of my time in MTA was on CIT actually). I have my take on how to build an RP that's also a game and not D&D levels of insanity (i don't like the wall of texts formula). MTA, SAMP and mods always have touched Roleplay, it was never that big. But suddenly GTA V's MP mods broke internet with streamers having 15k+ viewers playing on Roleplay servers. The RP they've there is much more like a Gmod darkRP with way less modding capabilities. It close resembles RP we see in MTA (mostly bad RP) but why now ? Are they doing something different ? Is it only because GTA SA is dated ? What are your opinions on this.
