I think adding graffiti or some kind of low level crime similar to it (vandalism) would be fun. It would also add more complexity to the “gangs” in Ventura. I’m not sure how you would implement it so that people don’t abuse the feature, but maybe having preset tags could avoid that. The graffiti spots could be set to only certain areas, like train tracks, bridges, overpasses, abandoned buildings, etc.) to avoid it being everywhere. The equipment necessary for it could be obtained through a quest, so it’s harder for everyone to get their hands on it. I think it would be a fun feature that adds to the “roleplay” elements of the game.
