Hello Raephi, the Surface is not suitable for games. The graphics card requirements are not met and the storage space of 128GB is also very tight for SIMS4. You can upgrade the memory with a fast memory card but even then it is not recommended. If you google, you will see that others have already tried to start SIMS4. Even when it starts, the game often hangs. So if gaming is important, you'd better buy a laptop with a dedicated graphics card from HP, Lenovo or ASUS...
