Games Like Rock 3

Rock 3 is a procedural world generator to build believable and interesting earth-like worlds. By simulating tectonics, erosion, and climate it drastically simplifies the process of building detailed and realistic biomes across continents and islands, while providing the controls you need to fine-tune and customize near-infinite possible planets. Export your worlds as equirectangular projections of biomes, elevation, heightmap, heat, water, and landmasses.

Rock 3 generates planets entirely on your GPU. It's not recommended to run this on a laptop or other device with integrated graphics. Your experience may also be compromised on an old or low-end graphics card. In some cases scaling the quality of the planet down can improve performance to usable levels. Maps are always saved at the highest resolution your GPU can handle, up to 8K.
