Ever play GTA: San Andreas? Fucking fantastic game. There were a lot of cool mods that the community made such as: Protect the President, RP, Manhunt, and Rivershell. Do any of you guys know of any mods/scripts/gamemodes from other games you've played that you think could be fun implemented as a Garry's Mod gamemode?
I always played Cops N Robbers in SA:MP but sadly such a large-scale thing wouldn't work in Garrysmod I don't believe any fun existing game will work in garrysmod due to its tendency to crash or the shitty playerbase
I think a stunt server would be pretty cool, although most likely wouldn't attract a very dedicated playerbase. Something that could be cool is a Zombie Roadrun gamemode (Completely made that name up) Basically you get in a car, and run over zombies. Maybe players get to be the zombies, the person who gets the driver (not really sure how this would work) get's to drive the car next round?
