Well, Bethesda games keep guards on you until you go to jail, pay the fine or kill every damn guard in the region. That's not bad and works as a motivator to be either a better thief or a more honest person in-game.
Of course, the fines are pretty low, so it's not a great motivator, but still.
What did you envision from 2077? Keeping in mind you'd want to try for a fun mechanic and not some new way of annoying the player.
Well, I don't want psychic guards. I hope it could all go on an identity tracker kind of thing.
1 - If we commit a crime and there are no witnesses and no CCTV, then we should mainly be in the clear.
2 - If there are witnesses, then we need to kill them before they have a chance of reporting it, which would not take long with the kind of cellular devices we would all be carrying.
3 - CCTV means it's tough shit and were on the run. We have to take out camera's first. (Of course that will only be in the corp zones and maybe a few in moderate zones.)
4 - If we use a weapon that is registered to us to bump someone off, then the police can come after us. But again, no psychic cops running from who knows where straight at us. They have to spot and ID us.
5 - Changing identity could be done in a number of ways. IF our description is going around, then a change of clothes should help reduce the chance of being spotted. Full face helmets and the like should prevent facial recognition, both during the crime and at a later date. We could also look at plastic surgery on our faces, it is in 2020 after all.
6 - If our SIN is known, then we would need to get that sorted out. We need a new SIN and that isn't cheap or easy. If we don't get one then every time we buy something with a cred stick or use a registered item or service, the police should know where we are.
7 - Our record should be vulnereable to getting hacked, but only by the best. If we specialise in NetWarfare, then maybe we should stand a chance of getting into NCPD's database and altering our record. Otherwise, we should just pay the next Rache Bartmoss to clear our name.
That is how I would play it.
Would we want to change any of the crimes and punishments from 2020?
