Before you put up the other two parts of this challenge, I thought it might be helpful for you if this one was analysed so that you can see exactly what we think is wrong with it.
subject #1=> 1 teen Sim
C.A.S.--->Teen w/1 or 2 parents and kill/delete them
Why not use the age sims cheat? Create an adult sim in CAS, then turn the age sims cheat on, and age the target sim down to teen. Healthier for your neighbourhood than creating useless, unneccessary character files. Deleting sims is a VERY BAD THING to do - this is a great way to stuff up your neighbourhood.
all cheats/hacks illegal---> if you use one at anytime after starting up the Sims you must not use any cheats immediate failure if you open up the cheat box
OK, so I'll take out harder jobs. That makes this challenge easier than my normal gameplay.
rewards are illegal---> if you get a reward you lose
The culinary reward is useless anyway, and the only asp reward I routinely use is the smart milk, so no difference to my normal gameplay here.
challenge ends when---> target Sim gets to level 10 in the culinary career or target sim dies
I can't even remember the last time I had an accidental death, so challenge will end when sim hits the top of the career. Short challenge.
you must only allow the Sim to get promoted without the chance card, you immediately fail if you use the first chance card (doing research on this concept right now; if impossible then I will remove this restriction)
Not hard.
you can only export/lose the parent Sim/s
Or create without parent sims, using the age sims cheat.
no Sim/s can join lot except for your Sim's mate if s/he's a Maxis created Sim
Most people I know create a custom neighbourhood for challenges, and many people at this site use clean neighbourhood templates, so that the only townies in the neighbourhood are those we created ourselves. Are you saying I need to replace my clean templates with the original templates just for this short challenge, just so that I have Maxis-created fugly townies for the target sim to marry?
Pointing System
-5 points for every time target Sim is demotion
Is it even possible to get demoted without using chance cards? I've never seen it, and I've been playing the game since before Uni was released.
+5 points for every time target Sim is promoted (if Sim gets fired or demoted Sim doesn't get points until the Sim gets back to the level it was at before the firing or demotion)
So a guaranteed +45 points for the 9 promotions (less if I send teen to uni, or get the job from the computer)
-10 points for every time target Sim is fired
See my response to the demotion point loss. Never going to happen without chance cards.
+10 points when Sim fulfills their starting L.T.W.
Easy. My CAS sims fill several lifetime wants, even with harder jobs in my game. Since I can't reroll the LTW (no hacks allowed), the only risky aspiration would be Romance with the possibility of woohoo LTWs - although pre-marital woohoo is banned, but not extramarital woohoo, so not so risky after all.
-15 points every time Sim misses work
Well, in the unlikely event that the sim misses the carpool, there's always the car.
+15 points if Sim doesn't get their first kiss (the wedding kiss does not count as the first kiss nor does greeting kisses
So no kissing, not even after they get married. Weird way to have a relationship, but it doesn't affect the outcome of the challenge.
-20 points every time Sim burns food or starts a house fire
Finally a penalty that might actually apply.
+20 points if Sim grows up well
It's not easy to have a sim grow up badly, on the few times it's happened in my game without me deliberately trying for it, it's because a grandparent has died right before the aging up - which won't happen in this game. So here's a guaranteed +40 points (grow up well going to uni plus growing up well graduating from uni)
-25 points if Sim has premarital Woo-Hoo
Easy enough to avoid if I don't have ACR in my game.
+25 points if Sim gets Woo-Hoo on their wedding night.
Well, duh. Of course I'd make this one happen.
-30 points if Sim uses buffet table or gets delivery
Easy enough to avoid this penalty.
+30 points if Sim buys fridge food from a local store
A bonus that can be exploited endlessly.
So most of your penalties are extremely unlikely to apply. You have an exploitable bonus for basically infinite points. There are no restrictions on things that should be restricted (such as choice of seasons, or going to community lots for socialising, or if jobs can be acquired from the computer, or any restrictions at all on uni).
If I were playing this, I'd set the seasons to permanent autumn for fast skilling and daily promotions, with Downtown at permanent summer for socialising. I'd send the teen to uni (permanent autumn again), get them in the right degree for culinary, visit downtown a lot to make enough friends for their career while still a YA, max out their skills (I'd make them knowledge so this may be their LTW), graduate Summa Cum Laude, then send them back home to get married, get laid, and get a job at level 9 culinary as soon as the job is on the computer. If their LTW career comes up before culinary on the computer I'd take the LTW career first for an extra LTW point bonus.
