500+ hours and 4 of my own servers and I stopped playing.

I've played a lot of Garry's Mod but I havent played in awhile. I've run my own DarkRP servers multiple times but I just have no drive anymore to play. Should I play again? And if so, what gamemode?

learn to code lua and make some fun things to keep you playing. you will get bored easily of most gamemodes because there is no progression.

Honestly, if you want to keep playing you should make servers and sell them to kids who don't know how to make em. Then you can ask for like idk VIP+ or some shit on their server to enjoy free premium content.
