The game starts in the womb and ends when you invariably croak, either by old age or pure Darwinian stupidity. The first choice you're presented with is in utero; whether or not you want to be born at one particular moment or the next. Will you be a disagreeable, stubborn little snot? Or will you go peacefully? The rest of the game carries onward in kind, keeping track of your statistics, interpreting your choices and affecting your character's ability to do everything from dating successfully to catching a baseball.
The game's many scenarios were written by psychologist Dr. Peter J. Favaro, and they are loaded with commentary designed to provide insight into your own personality (should you choose to play that way) and the consequences of deviating from it. Of course, the most fun you can possibly have with a game like Alter Ego -- or Fable and KOTOR, for that matter -- is to be as horrible and rotten a little bastard as you possibly can, if only just to see how quickly karma does away with your pathetic husk of a mortal shell.
Go get born and give 'em hell. Live your life the way you should have the first time through: making every moment as angry, violent and dangerous as possible.
