GameTree Linux uses the Cedega technology, but they've now discontinued their subscription service and evidently they plan to provide free access to the GameTree Developer Program going forward. Though this will be free, it will likely not be open-source. This quarter TransGaming will be releasing the Cedega Linux desktop tools through the GameTree Developer Program. The announcement found on GameTreeLinux.com is as follows:
TransGaming is pleased to announce the continued development of Cedega Technology under the GameTree Developer Program. This repositioning of the technology that powered the Cedega Gaming Service will allow the entire Linux community to gain free access going forward. Cedega is a cross-platform enablement technology that allows for Windows-native games to be executed on both the Linux desktop and embedded Linux platforms.
Although the Cedega Gaming Service itself is being retired, Cedega as a technology for the Linux gaming community will continue to be available as an active and invested toolset through the GameTree Developer Program. Free access will be provided to the various Cedega powered Linux desktop tools, game engines, and community features, with future technology advancements and updates being provided through this Developer Program to all enrolled members.
Beyond that, not many details are known. But will anyone actually want to use this Cedega successor? Cedega has been off the radar for a while. Meanwhile, CodeWeavers continues developing CrossOver and CrossOver Games with great results. Upstream Wine is also working very well for running most Windows games under Linux. TransGaming will really need to offer something different with GameTree Linux to make it a compelling option for running your favorite Windows titles under Linux.
We'll keep monitoring the situation to see what comes about with GameTree Linux.
