I have an important question for you guys! I bought Sims 4 for Xbox One a long time ago. Now I want to buy a couple of add-ons too. However, I bought Sims 4 as a disc and not downloaded it from the Microsoft Store. My question is: Can I download add-ons for Sims 4 from the Microsoft Store, even though I didn't buy the game myself from the Microsoft Store?
Of course. I do that with the Playstation too.
When it comes to add-ons, it's not about whether you bought the game on disk or digitally, but simply about owning the game. By installing the game, your XBox account will know that you own the game. And when you buy an add-on, these are not saved on the disc, but in the system for your account.
