Dude. I have fun with CITYRPG mod servers because There are SO MANY POSSIBILITIES AND VARIABLES added to the game. For instance, When someone pays me, I have choices and chances. They're buying a shotgun? I spawn the shotgun and kill them with it, then lock my front door and make my shop a blackmarket shop.
And that's just an example. The person could have killed me with hammer if I sucked more than I did at aiming, Or I could have forgotten to lock the door and police would have gotten me. It's all dependant.
The point I'm making is the City RPG mod is fun, Entertaining, and all in all useful for gameplay.
