Alter Ego, originally released in 1986, is a life sim. This is a browser version of the game, apparently unupdated (as indicated by, say, the lack of social networking, the total absence of gay people throughout an entire life). You start as an infant, make a bunch of choices, and see how those choices affect your alter ego. The game contradicts itself at times and occasionally preaches, but still. I tried playing through a life as someone pretty much the opposite of me, and found that my alter ego got reasonably wealthy, but completely unmarriable, and he died without children.
