Abstract Machine learning have a huge impact in video games, in this we will learn about use of machine learning in game development. Video game developers use machine learning to give users more realistic feel in the game. Non player characters (NPCs) algorithm are used to provide real like characters to the game and also increase the challenges for the players who are playing that game. Nowadays games are becoming more real than ever, we have to face more challenges in it. There are many games which are currently using machine learning and it might be the future for game development. Now games can also be experienced over VR (Virtual Reality), players can actually feel the game by just using VR technology, all thanks to AI.
