This brings back my fond days of Fisher price but I would love for them to bring in working civil service jobs. Be a policeman,fireman, postman, etc. Still have the socials but also have different job functions to go with it. Go out on patrol, get calls for burglars, shoplifters. Be able to respond to that bad cooking sim, and maybe start some new flames of romance..
I know some have done themes along these lines but I would love to have maxis do them.
Same along the lines of a Hospital, Prison, with careers meshed to these, so that when you leave for work you actually spend your work day doing something else.
