text: The company TransGaming marketed as a monthly subscription its own proprietary fork of Wine called WineX in October 2001, later renamed Cedega in 2004 and discontinued in 2011, which aimed for greater compatibility with Microsoft Windows games. CodeWeavers also offered an enhanced version of Wine called CrossOver Games. The reliance on such compatibility layers remains controversial with concerns that it hinders growth in native development, although this approach was defended based on Loki's demise. PlayOnLinux, established in 2007, provides a community alternative, with various guides being written on how to get games to run through Wine. A special Gaming Edition of Mandrake Linux 8.1 was released that featured WineX packed in with The Sims. The fact that the fork of Wine did not release source back to the main project was also a point of contention, despite promises to release code after achieving a set number of subscribers.
  2008–2011
  The Linux gaming market also started to experience some growth towards the end of the decade with the rise of independent video game development, with many "indie" developers favouring support for multiple platforms. The Humble Indie Bundle initiatives inaugurated in 2010 helped to formally demonstrate this trend, with Linux users representing a sizable population of their purchase base, as well as consistently being the most financially generous in terms of actual money spent. The Humble Indie Bundle V in 2012 faced controversy for featuring a Wine-based release of Limbo prepared by CodeWeavers, while a native version was later released in 2014. Humble eventually began offering Windows-only games in their bundles and on their store.
  In 2009, the small indie game company Entourev LLC published Voltley to Linux which is the first commercial exclusive game for this operating system. In the same year, LGP released Shadowgrounds which was the first commercial game for Linux using the Nvidia PhysX middleware. The GamingOnLinux website was launched on July 4, 2009, and eventually succeeded LinuxGames as the main source of news and commentary.
