Xbox Sims Island Life?

I have a question for you. Do you also need the normal Sims 4 on the Xbox if you want to get Sims 4 island life?

Yes you need.

You can check this simply by going to the software in the shop and then looking at what is included.

The following would then appear:

Contains:

Ledge 4.

However, the official Microsoft Store states that it is only compatible with Sims 4 and Sims 4 is not included.

Yes, because island life is not a game of its own but just a DLC
