With the rapid development of the video game industry, the issue of copyright of video games has attracted extensive attention from scholars at home and abroad, and a large number of papers have discussed this topic. However, the relevant papers don't reach a consensus on the concept of "Video Games" at present, which leads to a situation that the number of papers researching "Video Games" is mickle, but most of them are rather disorganized and unsystematic. This paper discusses the concept of "Video Games" and their classification, and analyzes the determination of the concept of "Video Games" and the significance of their classification in copyright law, with a prospect to contribute to the research in this field.
