While there is no eventual objective to the game, states of failure do exist in "The Sims". One is that Sims may die, either by starvation, drowning, fire, or electrocution (or from natural causes/age in certain versions). When a Sim dies, a tombstone or an urn will appear (in later expansion packs the Grim Reaper will appear first), and the ghost of the deceased Sim may haunt the building where it died. In addition, Sims can leave the game for good and never return, or two adult Sims with a bad relationship may brawl, eventually resulting in one of them moving out. Children will be sent away to military school if they fail their classes or if they have not fulfilled their needs (especially when hunger is very low), a social care worker will take them away from their household and they are no longer returnable.
