Alright, I couldn't find a thread for this so I made one of my own.
If I buy something from the Sims 3 store, do I need to have the Sims 3 installed to make the purchase? I uninstalled the game ages ago, so there's no Sims 3 folder and I'm not sure where any items I purchased would be stored on my computer. I haven't bought anything in ages so I don't remember how it works, lol.
