Valve Reveals Lifetime Retail Sales of Half-Life, Counter-Strike Series

Beloved developer Valve has released lifetime retail sales figures for some of its more popular games, including the Half-Life and Counter-Strike series, revealing that the studio has sold over 32.8 million games since the 1998 release of the first Half-Life.

Sales from Valve's digital distribution client are not factored in, with the figures only accounting for worldwide retail sales. With Half-Life 2, Valve began simultaneously releasing all of its PC games at retail and via Steam. The numbers were originally printed in the November issue of Game Informer, then republished by Gamasutra.

Furthermore, it was not specified if the figures of multiplatform games--Half-Life, Half-Life 2, The Orange Box--included both PC and console sales, or just PC.
