Only watch this if you've played Bioshock. Because it's full of spoilers AND you won't get it at all if you haven't played through the game or at least seen the scene referenced here. But if you have this video is awesome.
Have you ever wished you lived your life differently? Wonder how things would've gone if you had made different decisions in your life? Well, try out alter ego, an alternative life simulator.

For relationships, jobs, schooling, you have to click on the special icons for those even though you'll have some random events that will involve those too.
