There is quite a few features built into Identity for the criminal lifestyle. You'll see people robbing banks, taking hostages, mugging, growing illegal narcotics, fighting over gang turf, etc. We kind of see the criminal gameplay as a lifestyle in Identity, rather than a career. Committing certain crimes sets you down a temporary road of law evading, at least until you're caught and arrested. This will limit your access to vendors and shops around the map, forcing you to visit special black market dealers for all of your supplies. And there are exclusive clubs specifically for the criminal underground to meet and socialize with like-minded shady individuals!
