Generally I think various packs could use a little free update.
-Scarier looking werewolves.
It should at least be an option for them to not look like a furry. Better head shapes, more evil eye options and more intimidating teeth options could all help with this.
-Kylo Ren's Lightsaber available.
It could be a unique saber where you can't change the crystal of maybe, just existing as a set hilt/crystal combo. Could also maybe allow players to actually duel Kylo Ren while at it.
-Able to cut through the jungle with a lightsaber.
Just a cross pack thing that would make sense. Why the heck would someone buy a machete if they own a lightsaber, or would use their hands to claw through the jungle when they have a lightsaber in their inventory.
-More alien types.
Possibly along with a revamp perhaps, to allow us to make more varied aliens of very different kinds. Maybe with different abilities too.
-Robot customisation on par with Sims 3: Into the future.
Seriously, why can't they be customised in appearance? Sims 3 did this so much better, it's a huge step backwards. Let us pick different heads, torsos, arms and legs. Even a few options would already go a long way.
-Traits becoming more meaningful.
This is something that needs to be done across the whole game, including traits added through packs. It all just seems so meaningless as it is, affecting sim behaviour very little.
-Likes and dislikes affecting behaviour.
Sime should avoid doing things they dislike and steer more towards the activities they do like, engaging more in them on their own. Also switching the radio to a music style they like instead of hate dancing to disliked music and then get upset about it.
As it is I don't bother any more giving them likes and dislikes because it means nothing and I am tired of them getting annoyed at automatically doing what they hate.
-More options to deal with noisy neighbours in city apartments.
Should be able to isolate the place or something, it's very annoying.
