Video Game Development Online Diploma Programs: Development of games is undertaken by a developer, which may be a single person or a large business. Typically, large-scale commercial games are created by development teams within a company specializing in computer or console games. A typical modern video game can cost from USD$1,000,000 to over $20,000,000 to develop. Development is normally funded by a publisher. A contemporary game can take from one to three years to develop, though there are exceptions.
