Which one of the following do you want in a future update or patch?

How about all of the above?

I would honestly love most of these suggestions. I want to bypass cas or create a new save file without any sims.
The building options like walking out of a basement, spiral staircases and more options for roof placement would be awesome.

It was a very tough choice.

I just want spiral staircases because I can never fit the regular ones in small houses. When my Sims family grows I always have to purchase a whole new house for them instead of just adding a room upstairs because there is no room for the staircases.
I can't build (and I don't even like to try) well enough to change the house just to fit the staircases in, so spiral staircases would be a huge help for me.

If you didn't have spiral staircases as an option, I would have said "None of the above".

I don't necessarily "want" spiral staircases, but it would be cool. B)

the ability to create a brand-new empty save file with no Sims and all empty Lots because the premades have no storyline whatsoever. I also just want a bug free game.

The screenshot idea sounds like a memory system, which I would love, especially if I can jot down snippets about my sims' lives. The little family blurb on the world map doesn't give me the space to write the story I want to write.

I would love like allowances for the kids, and each family member can get payed their individual salaries from their jobs.

The treehouse or sims having individual funds.

Everything on the list, really.

Basically all of the above. I don't personally care that much about the roof and basement options, but clearly other people do, and I have no objection to it. Everything else: bring it on, please!
