High Maintenance trait

I haven't played with that trait, but I've seen Sims YouTubers use it and it looks extremely annoying. My understanding is that they're in an almost constant state of emotional debuff unless you send them to the spa, etc.

I personally don't like really overbearing moodlets and debuffs. I've recently started playing with Lifestyles again (which was a shock to me!) after I gifted a friend Snowy Escape and she had fun with them, but I also downloaded Bienchen's overhaul to make them harder to get and to make the debuffs less overbearing. Shock--they're actually fun like that instead of annoying!

On the other hand, one piece of feedback that the Team has been getting is to make traits more meaningful, so... I don't know why High Maintenance feels different to me from, say, hot-headed or gloomy, but it really does. Perhaps it feels artificial?

I agree. My sim would get upset every time she used the toilet or had a shower... I just use cheats to remove the buffs because it was too much. Being angry and tense all the time over everything is not high maintenance. I can see this being the case if you took them camping, but in their own home, it gets over bearing. 

I find sims tend to get more negative moodlets in general now. Workaholic sims become tense after work, with the vacation needed buff one day, then have 1 day off the next and are tense the whole day because they are not at work. What the heck do you want? There needs to be a better balance because I am a little tired of having to manage my sims emotions. I am suppose to be their creator, not their therapist! 

ok, but needing a vacation after you just got back from vacation is a whole mood irl. lol

but yeah, the high maintainance trait is not what I thought it would be at all.

In my opinion its by far the best trait in the game. I use it all the time. For once actually a trait with strong consequences/effects. I absolutely love it  :-)
