CBS Interactive Inc's game review website Metacritic.com released the 2013 ranking of game developers in January. The review website looked into companies that issued 15 or more titles, including PC games, consoles and arcades, in 2013.

The ranking is based on the quality of games measured by metascores, the Metacritic's proprietary scoring system that awards the top score of 100 after distilling the opinions of most respected critics writing online and in print to a single number, according to Metacritic.com.

Here are the top 9 developers of video games based on 2013 ranking.
