Do you think the devs will create better ways to spend simoleons in game?

It feels like they design a lot in the game for shorter play sessions so I don't think they would add items that would take a long time to buy, even if it is pretty easy to earn money in the game.

They probably should though, it would give us more reasons to earn a lot of money in the game except building and buying large houses, things like cars, stock trading and investments and yachts.
