Game engines are as varied as the genres and platforms of the games they help create. For instance, a studio aiming to craft a narrative-driven 2D platformer might find an engine like Unity — a veritable Swiss Army knife in the game development toolkit — a perfect choice, thanks to its versatility and rich asset store. On the other hand, a team working on a graphically intensive 3D MMORPG might lean towards Unreal Engine, with its high-fidelity rendering capabilities reminiscent of blockbuster titles like Fortnite and Final Fantasy VII Remake. I don't know any 3D engine using python as a main language, since 3D applications are, most of the time, required to have smooth execution speed. The driving force behind a large number of top triple-A games available today is Unreal Engine. This game engine has been particularly designed to perform many complex tasks more effectively than other engines due to its widespread use in that industry. The engine is open-source, like the others, which means the gaming community is constantly enhancing it.
