3D games are video games that use three-dimensional graphics to create a more immersive and realistic gaming experience. They allow players to explore virtual worlds from a first or third-person perspective, and often include features such as advanced lighting and shading, detailed character models, and realistic physics simulations. 3D games are typically more graphically intensive than 2D games and require more powerful hardware to run smoothly. They can be played on a variety of platforms including consoles, PC, and mobile devices. Some popular examples of 3D games include first-person shooters, open-world action-adventure games, and racing games.
