Assuming you don’t cheat, you spend 90% of the game working your ass off. Whether it be at work and waiting to get off, or working at home to better yourself so that you can get better at you job/career. That’s all fine and dandy, and admirable to a degree. Until you realize everything you do is a chore. Even entertaining yourself. All so you can have more and bigger things. But then, even if you accomplish everything you set out and tried for, you have very little sense of accomplishment, and then you die. Probably in a freak fire, or suicide. You can even beat death at his own game and continue living. And for what purpose? To hone up on your logic skill and get that promotion at work so you can sit there and wait to come home and do it all again.
There is no winning in the Sims, there is hardly even living. I guess what it teaches you is never try.
No, what it seriously teaches you, or me, is not to make my job/career my life. Work only when necessary to sustain yourself and be happy. And enjoy all those moments before you find yourself unenthusiastic about you achievements and die in a freak “accident”. [-FeistyRabbitSauce-]
Grand Theft Auto taught me how to navigate big city streets when I was formerly pretty terrible at it. [RocketPawnch]
