More Traits Mod #1 has 21 extra Traits:

• Serious sims tend to be Focused or Confident and are rarely seen in a Playful mood. They don’t get on well with Whimsical sims.
• A Stoic sims tends to be extremely even-keeled, and it’s very rare to see them feeling anything other than Fine.
• Peaceful sims just go with the flow. They’re not as affected by negative interactions and they gain Herbalism and Wellness skills faster. With the Parenthood Game Pack, their Emotional Control will increase at a faster rate.
• Daredevils live for the thrill! They have faster skill gains for Fitness, Rock Climbing, and snow sports, and they don’t freak out in the presence of uncontrolled fire.
• Logical sims think things through before they act, which makes their Mental skills develop at a faster rate.
• Whimsical sims often feel Playful or Inspired and excel at creative activities, especially the Writing skill.
• Shy sims like to socialize but they’re not great at it. Increasing relationships with other sims is a struggle for them, and they can get overwhelmed by being around Outgoing sims.
• The Grumpy sim is unpleasant to be around, as they’re easy to anger and rarely experience positive emotions. When nearby, other sims will get a moodlet to keep them on alert as to not bother the grump.
• A sim who is Sexist will have difficulty building relationships with sims of the opposite gender representation as them. With the Parenthood GP these sims will have a harder time building Empathy because of their ignorance.
• Generous sims love to give away money—even if they can’t afford it. The higher the relationship, the more money you can extort get from them.
• A Sincere sim is always honest and builds strong relationships. They do not get along with Evil sims and dislike performing Mischief socials.
• Endurant sims just don’t know what to quit. Their needs decrease much slower and they excel in tasks that require physicality.
• The Unforgiving sim holds grudges. Having a disagreement with them will result in steep relationship losses, and with the Parenthood GP you’ll find they’re not very good at growing Empathy or Conflict Resolution abilities.
• A sim who is Cowardly will get scared very easily and freak out at any sign of conflict. They have trouble growing their Fitness skill because they’d rather run and hide than try to confront others.
• Cunning sims make the perfect Politician or Actor, and their endless Charisma makes them good at convincing others.
• A Hedonistic sim is all about the enjoyable things in life, and this means their Fun need depletes faster than others. They have a harder time growing their Responsibility with the Parenthood GP.
• Spoiled sims get their way every time, or else. They get Bored and Angry easily and need to keep entertained or they will quickly get cranky. With Parenthood GP their Empathy, Conflict Resolution, and Responsibility will struggle to increase.
• The Judgemental sim has a harder time growing relationships because they judge everyone, and they love to gossip. They make for very emotionally distant parents.
• Warm-Hearted sims cherish their relationships so they decrease more slowly. These sims just want everybody to be happy & healthy.
• The Heartless sim doesn’t give two plumbobs about others, and won’t even cry at their funeral. These sims are good at Mischief and they thrive in the Criminal career. If you have Parenthood you’ll find that these sims pretty much never experience an increase in Empathy.
• A Pompous sim is even more judgemental that Judgemental sims and Snobs. They excel at Acting and really don’t concern themselves with the well-being of others, as the others are always below them. Empathy and Conflict Resolution decay at a faster rate with these sims if you have Parenthood because these sims think they’re better than everyone else.
