Requires about 19 GB of dedicated storage space.

Since the original full game is already around 4.7 GB, a 4 GB "highly compressed" version isn't actually saving much space compared to the original.

Typically range between 2.4 GB and 4 GB depending on the device and updates. 2. Can you run GTA San Andreas on 4 GB of RAM?

If you have a 4 GB RAM PC, stick to the Classic v1.0 version for the best performance. It only takes up about 4.7 GB of storage and will run flawlessly. Avoid the Definitive Edition unless you plan on upgrading your RAM to at least 8 GB.
