For a PC with 4 GB RAM, you'll need games that are not too demanding on system resources. Here are five open-world games that should run reasonably well on a system with those specifications:



  1. Minecraft: While not traditionally considered an open-world game, Minecraft offers vast, procedurally generated landscapes to explore and build in. Its low system requirements make it suitable for PCs with limited RAM.

  2. Terraria: This 2D sandbox game offers a massive world to explore, filled with resources to gather, enemies to defeat, and items to craft. Its pixel art style means it doesn't require much in terms of system resources.

  3. Stardew Valley: Although not a traditional open-world game, Stardew Valley offers a charming and expansive rural setting to explore, farm, and interact with NPCs. Its simple graphics and gameplay make it suitable for lower-end PCs.

  4. GTA: San Andreas: Despite being an older title, GTA: San Andreas still offers a vast open-world environment with plenty of activities to engage in, from missions to exploration and side quests. Its age means it should run smoothly on a PC with 4 GB RAM.

  5. Starbound: Similar to Terraria, Starbound offers a procedurally generated universe to explore, with an emphasis on exploration, crafting, and combat. Its 2D graphics and relatively low system requirements make it a good fit for PCs with limited RAM.

These games should provide plenty of open-world exploration and gameplay without putting too much strain on your system's resources. However, performance may vary depending on other factors such as processor speed and graphics capabilities.
