*in terms of the traits an alien can be born with, which is 8.
The whole motivation for this was to get a valedictorian in Evergreen Harbour. I've been screwed over before, so I was little nervous but Mu-hee got it.
And if I'm going that far, may as well go all-in. This is on normal lifespan. She had 76 traits when aging up not including the grief trait and promised inheritance, because those aren't permanent, but that wasn't the goal. There are a lot of easy to get traits she doesn't have (from werewolves, for example). It wouldn't be easy to beat 76, it won't happen by mistake, but it's definitely possible.
I was actually done with the 4 HSY aspirations on the previous weekend. If you make a point of finding your rival and being mean, you can check that off quickly. Her rival for Drama Llama was Max Villareal. After fighting with him for the Live Fast aspiration as well, she then wiped his memory and did a "besties" introduction. She had a crush on him, they got romantic, she asked him on 5 dates. Aliens are the easiest supersim teens. No question.
