Game Developer operates a site called Game Data Crunch, which publishes statistical data published by major game stores such as Steam and Epic Games Store. We have integrated the information collected on this site with the information on Steam Database , the official Steam database, to summarize the information about the game engine used by the games distributed on Steam.

Included in this statistic are 'games released after 2010', 'pre-release games', 'free games' and 'price less than $ 4.99' unless otherwise stated. 'Games released in' and 'Games with less than 50 reviews' are excluded. This is to reduce noise from statistical results by excluding 'game projects born from small hobbies' that are far from commercial efforts. In addition, it seems that the total number of target games has exceeded 10,000 even if narrowed down under the above conditions.

Unity is the most popular game engine for mobile game developers, with over 50% of the mobile game market using Unity. That's why Game Developer says, 'I was curious about how popular Unity is in PC games.' However, research has shown that Unity may have an even greater share of the PC gaming market than the mobile gaming market.

Metacritic. With RPG Maker at 7% and Ren'Py at 3%, it's 'very difficult' for titles with two game engines to get Metacritic reviews, Game Developer said.

It points out that it is a harmful effect that Unity is adopted.
