Rebuild and remake the whole town challenge?

I did this a few years ago. I didn't delete very many townies, but I did bulldoze all the EA houses and replace them with much, much better ones from the gallery. Then I added in Sims of my own creation and lots of public venues for them to entertain themselves. Since this took a really long time and I really don't ever want to do it again, I have that save backed up in about 4 different places and it's what I always use when I start a new game. It's worthwhile, I encourage anyone to at least give it a try.
