I had been using 1.1, but there is something called the Virtual Sims Toolkit, which allows you to backup and restore up to 5 games. So, if something goes wrong, just backup your game and start from there, or even have up to 5 games playing at once. I would have loved this my first time through, when I had 9 females and no males...anyways, my question is, is 1.1 significantly better than 1.0? They seem a little different to me, but pretty much exactly the same so far.
