Morrowind is an enormous proprietary game loved by fans for its atmospheric and immersive world filled with bizarre giant mushrooms, homes built into giant vines, and barren wastelands. However, it was plagued by software bugs, had many elements that were half-baked in their execution, and its game engine took poor advantage of GPUs. Some of these problems fans were able to address with unofficial patches and mods, but others could not be solved without changing the actual game engine.
