Desurium client published under GPL v3

One way or another, but at the moment, Desurium is the only free distribution platform for games. This is its advantage over Steam from Valve Corporation, although Desura developers themselves do not talk about competition, but rather try to “complement” Steam.
Desura specializes in independent games. Now in the catalog there are 110 games for Linux, of which 33 are free.
For comparison, Steam has 1504 games and 40 million active accounts in the catalog. The largest publishers are located there, including Activision, Rockstar Games, 2K Games, Sega.
