Sandbox games give players open-ended freedom to experiment, build, and play however they like. The farming and crafting loops of Stardew Valley, the chaotic playground of Grand Theft Auto Online, and the wasteland tinkering of Fallout 4 all reward creativity over rigid objectives. Expect flexible systems, emergent possibilities, and tools that let you set your own goals, whether that means constructing, exploring, or simply seeing what happens when you push the rules.
