In the opening scenes of "Luigi's Mansion: Dark Moon" Professor E. Gadd's paranormal research laboratory is running smoothly. Ghosts are helping him out with his studies by sweeping, writing on blackboards and doing odd jobs. Even apparently shocking each other with electricity, but it's taken as a great joke and everyone is smiling and laughing. It's a light-hearted scene of idyllic employment, as often seen in family friendly games. Maybe especially Japanese games. People enjoying even the most mundane and repetitive jobs, and knowing that eventually hard work will lead to results.
