Coming from a semi-mathematic mind, and definitely one who likes to make a million lists... spreadsheeting comes pretty naturally to me. I've been making spreadsheets to track my Sims playthroughs for years now. It's only occurred to me recently that other people might be interested in them, too. So here is where I will keep my growing list of googlesheet FREE spreadsheets. And yes, this list will be growing. I am actively working on at least 3 tracking spreadsheets now, although my website moving had to take precedence, but I will be getting back to them.
Super-Sim Tracking Spreadsheet
Not-So-Berry Extended Edition Spreadsheet (by EmilyBlueJaye)
Timeline Adventure Challenge Tracking Spreadsheet
