Urgencies

Urgencies are the common needs, such as Hygiene, Hunger and Energy, that Sims must fulfill. When a need becomes too low, a Sim might have a cloud with the image of that need over their head and will make a motion, such as holding themselves if they need to use the bathroom. Sleeping Sims with low needs often have nightmares about the low motives. Sims with low needs tend to wave at the player and complain, and will not learn any new skills until their mood improves. They will also refuse to do several actions. Visiting Sims whose needs fall too low will leave in order to fulfill them.

If needs are not met at all, consequences might occur, such as having an accident on themselves, passing out, or even death. In The Sims 2, Sims who are suffering from lack of social activity will be visited by the Social Bunny. In Open For Business, if a Servo's power need is low, they will automatically go to recharge. If cancelled out too much, or if it's nighttime (which will cause the power need to get worse), then the Servo will crazily run around and break. In Seasons, if a PlantSim's sunlight/water need is too low, they will run outside, and might just pass out.
