Welcome to Unity

What is Unity

Unity is a game development engine used to create both 2D and 3D Games.

Introduction to Game Production

When designing games its important to take into consideration the following :

  • Platform on which the game will be played
  • The category and genre of the game
  • Demographics of the players

  • Video Game Platforms and Genres

  • Describing the Game Production Pipeline
  • Game Development Jobs and Roles
  • The Game Design Document
  • The Technical Design Document

Video Game Platforms and Genres

Game Platforms

Unity is used to create games for the following platforms :


  • Windows
  • Mac
  • Linux


  • Xbox One
  • Playstation 4
  • Wii U

Hard Core Games

  • Designed for the console platforms
  • Feature long missions and quest
  • Complex game mechanics
  • Required a lot of compute resources
  • High graphics quality


  • Designed to played in short burst of time
  • Designed for mobile
  • Designed for hardware with constrained resources
  • Feature simple game mechanics, e.g aracade, board, platfomer styles

Game Markets

When designing games you need to consider the market for the game. Games are services and varying monetization strategies raises the stakes for a game to engage users and develop different means of reaching and motivating users to purchase.

Here are the game markets by numbers :

Game Market Stats

  • North America 32%
  • Latin America 4%
  • Europe, Middle East and Africa 28%
  • Asia and Pacific 36%
