(a) Simulated Life Game.
1 - SimCity 4 is one of the obvious examples of the widescale SLG (that is, the simulation of several lives on a wide scaled locale,) as are some of the other Sim games from Maxis / EA.
2 - The Princess Maker games are an example of the narrow scale SLG, in which you tend to one simulated life (sometimes more, though not on the scale of the widescale SLGs.) These tend to be more detailed as far as character growth is concerned (details may include habits, mood, state of body, etc.
(b) Social Life Game
A game in which you take control of someone's social life. While The Sims
could fall under this category, this definition truly pertains to the ren'ai
gaming style (the "love sims" if you may) that include most visual novel
s and practically every dating sim
What friggin' example? Okay... The Sims is a great SLG, but all these expansion packs are hurting my wallet!
