First, a huge thanks for coming up with and hosting these challenges. I really enjoyed this
My mom was human and self employed as a painter, dad was a genie and an alchemist. Painting was easy to stop and start and bring in money in between meeting needs of babies. I chose genie for the instant cleaning and perfect food summoning abilities (for Baked angel food cake moodlet). Though I debated vampire, too, I decided the genie was the better option until I could get the motive mobile. I planned to change him to a vampire afterward, and forgot. Oops. All of the boys except one were genies, and all the girls were human until my very last female nooboo--a genie. As soon as he could, I had the dad make a midas touch elixir and turn statues into gold.
Dad changed most of the kids to vampires (or other SNs as needed) with potions, but I also assumed "cake up" was a rule. Oops. I played in Moonlight Falls, and then had issues with collections--there didn't seem to be enough spawners to complete metals (only seemed to spawn gold, silver, iron, palladium), beetles or butterflies, so each child did gems. That was the most time consuming, because 6-8 of the 10 were easily found most days, but then I'd get stuck waiting for the rarer gems, and multiple kids needed the same ones. I did place some of the missing community lots, however, so that may have been my downfall, seeing as MF has the "glitch" where an empty lot has to be deleted because the game thinks something is there (hmmm.... now I assume those lots contained spawners, so not a glitch).
I ended up with twins most of the time, after mostly trips in my practice. Twins were easier/faster for sure (and though I didn't have time to try it out, I think I would have ultimately ended up with a higher score using twin births due to time saved). I had some of my YAs buy collectible LTRs and then transfer them to the parents on moving out. I sent my kids to the lot next door to age up as often as possible, but didn't have the forethought to consider graduation, which caused delays for some of my YAs.
Wish I'd known about the stroller trip bumping the relationship quickly, and using move objects for gems and metals.
Nooboos were given the Friendly and Neurotic traits, children were given workaholic, and teens inappropriate for the ability to kiss a potential RI. YA was given a random or LTW appropriate trait if I was able to choose. Teens immediately got a job and worked from home in order to get their first promotion on the first day of work.
I had fun trying out LTWs that I've never attempted before, but I know I could have done so much better if I'd taken the time to practice properly beforehand. I came close to throwing in the towel with the constant crashing/clearing caches/restarting that probably only allowed me to play for 20 out of every 30 minutes. So with that said, I'm not going to wait to start the gnome challenge
