How many worlds/save files do you have?

I have my template save which i use for starting new stories -- actually I'm about to make a copy of that save and do the Strangerville story again (previous template got corrupted and festivals weren't spawning so I've had to start over). I also have a save I use for testing as well as for working on builds (mostly remodels since I can't build worth a lick), one save that has all the worlds in pristine condition (if I need to replace a venue) and two save files (Plumbella's and lilsimsie's) which I use as resources for buildings and families. I have one more save file planned -- I'm going to delete all the Sims from the template file and add in the Sims that Maxis has been uploading like the Newbies, the Smiths, etc. Eventually I'll be playing that save but it's more of a long-term project; I'm hoping they'll upload some of the Veronaville families from Sims 2 like the Montys and Capps, maybe the Summerdreams if we get fairies in a future pack.
