If anyone cares to know I just found out late last year that the sims 2 on PC (with all the expansions) has some interesting concepts. if you click around through the game different sections including a way for your sims to play in the stock market and lose and gain money each day. In which makes me wounder why the stock market exists in real life.
The Sims 2 series on PC, I'm finding it, to be better then The Sims 3 series on PC. Of course you need to download mods to make the game run better like the hoodchecker and the rare BO's mods in which will automatically clean up all the junk data the game collects while playing. and allow the game to run better (but not perfect)
You still should never erase any sim using the in game delete button or even delete user data files because it shreds part of a file and leads your game neighborhood in corruption.
I found out that as long as you don't create a bunch of in game people characters, you can also have your neighborhood last longer., and you should never delete any of the sims tombstones or allow sims to autonomously smash or kick tombstones because if that happens your neighborhood will freeze up at the loading screen load up a lot sooner.
So far I do not know if the Sims Life Stories has the same issues as the main The Sims 2 series even though the The Sims Life Stories and The Sims Pet Stories I think uses the same game engine.
to play the stock market click, fool around in the asperation rewards menu and add upgrades on the finance department you need to play with a sim a while with the fortune aspiration to unlock the stock market and other interesting features that are hidden with all expansion pack (of the sims 2) installed
