It is the best-selling German-language magazine focused on PC gaming and it also hosts the largest video gaming-related portal in the German-speaking internet.

[2] The magazine also comes with a DVD, which features Demos, Mods, video-reviews as well as a full retail version of a videogame.

By the fourth quarter of 1999 it sold about 333,000 issues per month, in 2000 it overtook competitor PC Games as the largest German language videogames magazine in Europe.

[7] IDG also started GameStar sister magazines in Italy, Poland, Hungary, the Czech Republic[8] and the United States.

The US version was, quite differently from the rest, positioned as a magazine for adults, about PC and console games, similar to inCite.

[9][10] In April 2015 GameStar and its sister magazine GamePro were sold by IDG to the French publisher Webedia.
