Timeline of events in The Sims series

Every Sims game takes place in SimNation: a country located somewhere in the world in which the games are set. In the series, SimNation is shown to be set around the 1990's, 2000's, or possibly even further on. It shows modern, real-life technology such as TV's, cars, and computers - but also some futuristic, advanced technology such as Servo and the Teleportation Pad. The locations of The Sims games could be anywhere in the world, or even in a completely different universe altogether.

When trying to construct a timeline such as this, order of events often has to be inferred, or outright guessed-at, so the list for any period may not be in exact chronological order. Regardless, here is an incomplete timeline of the entire The Sims Series as of February 2010:

Possible Future
Based on evidence from the previous games, the following events may possibly happen between The Sims 2 and future games, should there be any. For example, it is possible that Mortimer Goth will die, or already be dead, in a future Sims game, as in The Sims 2 it is indicated that he is very close (about 8 days away) to dying of old age. There are also other possibilities, such as Don Lothario leaving Cassandra Goth at the altar, which is very likely to happen in The Sims 2. Please note that these events are not confirmed by EA and are purely speculation. Here is a list of events likely to happen in the future:
 * Death of Mortimer Goth
 * Return; or death; of Bella Goth
 * Don Lothario leaves Cassandra Goth at the altar
 * Don Lothario impregnates Nina Caliente or Kaylynn Langerak who gives birth to an illegitimate child (this not indicated or even hinted anywhere, but since Nina is quite attractive and has the Romance Aspiration and Kaylynn is Don's favourite lover, it is possible that Don, being the love 'em and leave 'em guy he is, may father a child with one, or both, of the two)
 * Cassandra Goth gives birth to a daughter named Isabella, fathered either by Don Lothario or Darren Dreamer. (While this is not hinted at in the game's official canon, many players seem to believe that Cassandra's first child will be a girl named in honour of her missing mother.)
 * Alexander Goth goes to College (again, this is hinted nowhere but he is somewhat of a genius like his father and it's likely he would)
 * Lilith Pleasant breaks up with Dirk Dreamer and marries Dustin Broke, at the same time as the event below (this is thought to happen, as Dirk is the complete opposite of Lilith)
 * Angela Pleasant breaks up with Dustin Broke and marries Dirk Dreamer, at the same time as the event above (same reason as above)
