Pricing Overhaul
We need a pricing overhaul, badly. Items across different packs were priced by people who weren't even attempting to match the pricing structure of other packs, and so many things in buy mode make little sense. This also makes finding items very difficult because you scroll too far trying to find pricier things and they're way too cheap.
Immediate example: Guess which of these fire pits is 450, 350, and 150 simoleons. Did you guess left to right? Wrong! Other way around. The one that's rocks with crummy logs is 450, the one that's better rocks with nicely stacked logs is 350, and the giant one is 150. There's another giant one with nicely stacked rectangular rocks...and it's also 150.
Go look at the swingsets and tell me which ones you think would be costlier...because they're not. They're just random prices. Despite being the same basic object with no benefits or downsides, they're randomly priced.
Many major, major activity items also just have bizarrely low prices in general. The Celestial Crystal Crown- a literal gilded crown that you can slot gemstones into for magic healing powers- costs...100 simoleons. It costs less than ordering two pizzas to have a permanent source of magic powers. Shouldn't something like that be a big-ticket item? I would say 10,000 minimum for something that powerful.
From game consoles to TVs to bookshelves to any and all activities, nothing seems priced correctly anymore. Base game windows were very expensive, now much larger much fancier windows are very cheap- we're talking 250 for a small window in base game and 35 for a massive extravagant window 10 years later. This issue clutters the catalog and unbalances the game's admittedly historically shaky economy.
Bigger, better things should have bigger, less achievable prices- as a drive to make money and have an excuse to spend it.
