Can someone explain why DarkRp is so popular

idk im just asking, DarkRp is just a RP tho , but why its so popular?

I think it's because in darkrp, there's a lot of RP possibilities

Because of YouTube On Gmod, From Over The Total Video Material On Gmod 70% DarkRP and the desire to find a good server, the audience starts playing on one server, and this mode is delayed
