City RPGs tend to be lame because either the jobs are just linear automatic paychecks, it's entirely cops vs robbers, the admins are abusive, or the build is just a square grid.
Wentworth/Diggy's City RPG is a prime example of what a City RPG should be like.
The old topic is still up too, link
here.
Diggy's mod is long gone and private, to my knowledge. Iban also put out a completely updated mod (link
here) but that, also, is private.
tbh, to my knowledge Iban's City RPG is the only public City RPG addon. All others are private, or just unlisted.
