Games in a nutshell – Where do game engines fit in?

The game industry netted a total revenue of $120.1 billion in the year 2019. A number that dwarfs Hollywood and the entire music industry combined. Games are an amalgamation of technology and art, where programming meets animation, music, stories, aesthetics, and 360 no-scopes. So, how exactly are games made? How do artists and programmers create an immersive, interactive experience that often ends up being better than any other form of entertainment out there? The answer is game engines.

If games are a simulation of worlds with varying levels of artistic liberty, then game engines are responsible for the rules that govern the simulation. In other words, they let you play god. Game engines lay down the software framework upon which games are built. Support systems such as lighting, rendering, Automatons, physics, animations, music, and sound are a few examples of such features. Game engines have come a long way since their inception in the 90s. They are IDE’s for games just like eclipse is for Android apps. A complex, powerful, and fully featured package that is easy to install and get results from.
