From what I've read here, this challenge is so much fun! I've just started this challenge tonight - I was going to wait since I've got plenty of other games going, but I've been excited all week, so I figured I'd better catch that energy now.
Amelia Echo is my sim and she is an outgoing music-lover, circumstances have made her a bit...well unstable. She a bit of a renaissance sim, wanting to do a bit of everything, well, being forced to do a bit of everything. You see her "room" is a ship. Amelia's been stranded deep in space. Those who were with her are now gone (there were 7 others living with her originally), but now she's by herself. Although the Mansion Barron is the end-goal for story purposes, she's not aware of that aspect of the challenge. She's just going to go about her daily life trying not to go too far off the deep end and hoping, but despairing, for rescue (It's already been years).
My "room" is a bit unconventional to match the back story. I've cobbled together her rooms from the full ship that's shes using. Although technically there's much more to the ship than you see in the game. It's around 64 square feet plus about 8 squares to make the hallway work and then the extra spaces where she can't go anyway so I don't worry about them. Do you suppose the mail can be delivered underground?
I'll be keeping score (I'm at 99 right now after finishing day 1) and the story will be on my blog. (raereigames.wordpress.com)
