I will be starting a new Legacy game tomorrow. My niece came to visit me and decided to start one herself, and she was having a hard time finding a spouse for her Founder, and thought she had found the one and married him. Once she did she realized he was in the BFF household (which is against rules for moving a spouse) so she had her sim immediately divorce him, it was the most hilarious and tragic thing, and I have a few screen shots of the occurrence that I will edit and post later. Just too funny not to share.
Great start to the Legacy, I look forward to checking on it in the future.
