Do you multitask(in RL) while Simming and will you do it with Sims 4 also?

Yep and yep :D It worked better for TS2, though. Little bro and I had competitions to see who could clean their room the most during load times. I would also put the game on speed 1 when sims were at jobs and deal a deck of solitaire on the floor or play with my cats. Otherwise I just left the stereo on in game and listened to music when they worked. If I was bored with the sims, then someone stayed home and didn't work and went on adventures.
