Okay, what's this Legacy thing? It sounds intriguing, is it like a challenge, or just a plot device?
its just when you set up a sim/family & don't use any cheats along the way & you can't have them do certain things if you choose.Then it goes to all their generations of children & then their childrens children.Check my legacy about the Thompson family (page 2) & you'll see what I mean by it following generation by generation
