Minecraft

The best-selling game of all time (300+ million copies) is also one of the coziest — in Creative mode. No enemies, no hunger bar, no fall damage. Just infinite LEGO in every direction, with a procedurally generated world that goes on forever. Peaceful mode in Survival still has exploration, mining, and building but removes hostile mobs, offering a stress-free alternative that outperforms #2 Stardew Valley in creative freedom. Minecraft's modding community has created entire cozy sub-genres: cottagecore builds, lo-fi farming, underwater bases with ambient jellyfish. It's been used in therapy, education, and urban planning. The game is whatever you want it to be. Over 140 million monthly active players enjoy its tranquil sandbox.
