I'm currently in the MediaMarkt and looking for a laptop for a maximum of 400 euro. (It's Black Week right now) It should run smoothly, most important!
Look that he has a dedicated graphics card or an AMD ryzen with APU min 3000 series but we have a hard time finding something at the price
Think again about your requirements.
This one seems to be able to do what you want:

But I don't think you'll be happy with it. Apparently it even has the recommended requirements for sims 4.
Only in principle, notebooks in this price range are not suitable for gaming. Do you ever want to do something other than typing and Sims 4 will surely reach its limits quickly.
A few hundred euro more or, even better, a fixed PC would certainly make more sense.
At Mediamarkt there isn't that much choice, and I don't know what the offers are.
But online you can find enough devices that come into question:

I would recommend a notebook with Ryzen 5 3500U, which is ideal for your requirements. SSD is also a must, but is actually standard for devices with the CPU.
Edit: @Asporc's offer seems to be really good!
