This seems like fun! I've read through the instructions, but haven't started/tried the challenge yet, so let me see what questions I have so far.

Sitting on the couch - do you add 1 block and a living room-related item *every* time they sit on the couch? That seems like it's gonna be overpowered, but I haven't tried it yet.

Handiness skill - Above, you say that we must force the sim to repair broken objects. How would the sim ever learn handiness independently? Will they read skill books by free will?

Music skill - can we earn blocks for more than one music skill? I.E., if the sim learns violin first, can they also gain blocks from each level of guitar they learn?

What happens if a sim's area gets blocked off to the point where they can't expand without encroaching on another sim's space? For example, left middle sim expands to the left and up a bit, middle top sim expands down. Their spaces touch and block off the area around the top left sim's room, and they can no longer expand. Do they lose? Does their room get deleted?

What happens if a sim dies? If they catch on fire or are electrocuted or doesn't feed themselves?

Thanks so much for this challenge suggestion!
