Feedback: Share with us what you would want to see in the game

I would love to see spiral staircases, more stair options and even an elevator you can use to travel between floors, like in TS3.
You've given the ability to create animals with eyes in two different colours (heterochromia) and I'd love to have that choice with my Sims as well.
More tattoos! I love adding ink to my Sims, but there's not that much to choose from - maybe some more sleeves, back pieces etc?
As has already been suggested a couple of times... ground level hot tubs.
Piercings! Facial and maybe body.
I know Jungle Adventures has just been released, but maybe another vacation spot, like TS3 Island Paradise, that was a great game pack and I loved being able to scuba dive and build houses on the water.
