I agree. This is an old thread, but I'm bumping it up, cause even with the "new" 10000 point traits, they aren't really adding a new gameplay aspect. So, I'm gonna add some traits I might want/can think of, and hopefully others will chime in as well, cause I bet there's a bunch.
Sickness immunity. Since sicknesses are now a thing. Get rid of those inconvienient colds.
Loyal. Will never autonomously flirt or respond to flirting with anyone but their chosen partner.
Treasure hunter. Makes it more likely to find rare collectables. If a simalready had that trait from the collector aspiration, this would stack with it and make it even more powerful.
Iron stomach. Makes you immune to discomfort from eating bad food AND immune from pufferfish poisoning.
Fireproof. Can no longer die from fire, and also doesn't get tense or panic around fires.
And that's all I have for now, I may add more later. What would you like to see as reward traits?
