The conversations can be interesting to put it mildly. When I get the chance to play, I mainly play a police officer and it has caused more than one moment of confusion when I didn't realize my partner had taken a work call and their co-workers could hear me barking out "lawful orders" from the other room.
Roleplaying games are really great for exercising your social skills and creative expression though, that's for sure.
FiveM is the most popular platform for this type of modding, and is the one I use. nopixel is the most popular server on the platform and usually a good place to start getting a feel for what's possible on a modded GTA server.
If you check out https://nopixel.hasroot.com/, they maintain a list of all Twitch streamers currently streaming nopixel.
My side project currently grosses close to $1,400 per month through Patreon.
I run a modded Grand Theft Auto: V roleplaying server with around 1,500 members (around 300 really dedicated MAU.) If you're not familiar with GTA RP, it tries to emulate real life as closely as possible while still recognizing that GTA is an arcade game. Players live lives as if they were real people, buying cars and houses, holding jobs, opening businesses, receiving medical treatment, being arrested, etc.
I've spent around three years working on the gamemode and spend, on average, 30-60 hours per week on it. It's really a pure passion project. Players support the project through Patreon in exchange for priority queue access (when the server is full, players are held in a queue until a slot opens up for them), custom license plates on their vehicles, custom phone numbers, and other cosmetic perks.
