What is a game? It’s often hard to define. A good way to examine what is a game is to look at parts of a game. Throughout time and across cultures, most games have the same six parts – a goal, a challenge, core mechanics, components, rules, and space. Understanding parts of a game opens up the world of game design because with this knowledge, you can change one part of a game to create a new game (called modding) or design your own unique game by taking all six parts of a game into account.
