Honestly you can find some fun in TTT/DarkRP, but even now there are still hidden gems and new gamemodes being released. The problem is, they're buried under more popular modes and, usually, end up dying and unsupported. Making new maps is awful because of the ancient level editor's sheer lack of modern quality of life features and insular knowledge.

Content creation as a whole is a painful hell-torrent to get through, especially as a beginner, but once the stockholm syndrome hits hard enough you can see the matrix and pump out some decent stuff until you start to stretch the limits of the engine and yearn for more.

Aside from some occasional source engine nostalgia, I probably wouldn't ever touch this game again purely as a player. But since I like to make stuff, I still haven't dropped gmod.
