Aw, so close. I thought I may of had that one, but congrats to
@GlazeyLady for her win. I also wanted to say how fun this challenge was, and it was a nice change of pace to have a parenting type challenge without a full house.
Anyway, my strategy was evolving. I had so many questions before I started, and so many more came up as I was playing. I had never played with aliens or vampires before, but it turned out strategy was pretty much the same for all three life states.
My first thought was it would be a lot better if they could have twins. On my first practice run, my humans did manage to have twins, but not the aliens or vamps. It is so unreliable, I knew that I couldn't depend on that for strategy. As, I played though, I realized one child is better anyway. The most time consuming part of the aspiration is helping with homework for 4 hours. At first, I just had one parent help them with their homework and it takes 1 hour. I knew if they could get a B, that they would have extra credit as well. I found out if a child goes to school with a completed project and very focused they could get a B in one day. That was great to know, and it did help the time by sending the kid to school the next day, getting the B, and then There would be 2 hours that homework could be helped. Although, that still wasn't the fastest way.
While I was doing the alien practice, my kid and his dad kept talking autonomously while his mother was helping him. I noticed that his homework took longer to complete, so that's when I knew. Of course, what makes everything take longer in sims 4, multitasking. So, when i used that strat, I had one parent helping the kid with homework, one parent sitting at the table beside him, and I just kept queuing up social interactions for the kid and the other parent that wasn't currently helping him. So, by doing it that way, I could get about 6 hours of homework help out of just one homework. That completely took away any need of getting a new homework.
So, this is exactly what I did. When the game first starts, I made a club with both parents in it. The only club activity I put at first was friendly interactions. Then, obviously, I had that parents try for baby. It happened the first time for the humans, but the vamps and aliens took twice. Then you have 3 days until you can have that baby, so I used that time by maxing the parenting skill. First, they read the parenting books. Then I just had them talk to each other and every couple interactions, I would have them give parenting tips social. The first night they slept, and I added sleeping to club activities. When they woke up, they had enough points for rally the troops. They only other perk I bought was a parenting skill boost. I did find that rally the troops really wasn't very beneficial for the vamps though. Also during that time, I had a caked baked. As soon as the baby was born, it was aged up to toddler. Then the toddler was aged up to child. I gave the children the good trait because it gives you a third of the bar to empathy. The first thing I had them do was play with the doctor set and queued up all of the praise playing with the doctor set as I could with both parents, that got that discipling your child 5 times milestone done, and helped with the empathy. Then I cancelled the playing, and had the child do homework like I described above. Once one parent had their 4 hours, I would switch to other other parent for the remaining 2 hours. At that point, the child went back to the doctor set, fill up the parent's queue with praise, then cancel the playing interaction. Then, start playing again, filled the parents queue again, and empathy was filled. Then, it was time for teen, so the cake had candles put on it again for the child to age up. I gave the teens the neat trait because it fills up manners a third. First, I finished the last two hours of homework for the parent's aspiration, then had them praise him about homework just like I did the doctors set by queuing praise, then cancel, start homework again, and queuing it up until responsibility was in range. Lastly, I put a bunch of tables in the yard, and had the teen set them all. While the parents were running around praising him or her for setting the table. So, they were finished around midnight or 1 early Thursday morning. I kinda messed up on the vamps because if they already have full parent mode when that part of the aspiration is there, it won't complete, so you have to wait for the moodlet to go away to get it to come back again. I lost a hour there. I also lost a hour from the vamps and aliens not getting pregnant the first time.
So, I am really looking forward to reading what glazeylady did. I'm still really happy with my score because if I didn't do all the practice I did for this, I would of been somewhere in the middle probably. I pretty much stuck with the character values I chose, and didn't really experiment with that, so that may of been where I could of saved more time.
