Hmm it's tricky. :/ I have a decent amount of hours on GMOD and it really depends... Most kids who play don't really like to build things and are sometimes impatient. A lot of the time they just want to mess around with something that don't require much effort for their own amusement; like dupes on the workshop, addons and players. For them, it's requires less effort to annoy a player for satisfaction than to create the perfect money printer system that churns out cash.
It's because of the large amount of streamers and youtubers, and the fact that it has a rather hefty player base already and has just about any gamemode.
Yeah, I know. The good part is, other game modes are available. It's really a matter of finding a good community. I think in principle the DarkRP addon gives a lot for what kids want to do.
there is really nothing we can do about what age playing the game you just gotta deal with kids and move on or just ignore them and dont even talk to them
