It really doesn't require much thought does it. If I had to rate the game on which age group it required to succeed and or have the Sim be happy, I would say age five or so. MySims might require more thought than TS4 and more strategy of how to get Sims out of trouble (since there is none in TS4) and possibly require more ingenunity on the part of the player than TS4 does. There is very little challenge in keeping the Sim alive, or overseeing their happiness or not. I have literally walked away and left it running and nothing happened other than the Sim remained bascially happy for hours and lack of money meant nothing either. Power off was no big deal to the Sim. Why should it be when they can just whip out their phone for ten hours, never needing recharge, and never die from accident (extremely rare) or starve. It's like turning on the TV and then just leave it on and go do something else, it's no challenge at all to keep the Sim happy or healthy.
