errrr
im feeling very very wary of the "can do anything in real life" part because the problem with game development is there's never enough time to make a game as big as you want it to be, and that's for AAA games like GTA. and given that this isn't backed by a AAA dev or studio there's going to either be a massively long wait until this game is out, or its going to be less exciting than it sounds at the moment.
and unless they're simplifying things like jobs and stuff its not going to be very fun. this is already ignoring the potential for mass scale griefing and violence/criminals as alkatjo mentioned.
the real likelihood is that anyone who would otherwise go out and join mobs and forget other people's stuff up but dont because of real life consequences will end up doing it in game because there is no consequences to it.
