Ryzom has joined those small ranks, with the release of an official Linux client for the game. This goes hand-in-hand with the game's move to open source earlier in the year, which allows players unhappy with the official client the freedom to make a number of alterations.
To celebrate the official Linux release, Winch Gate is holding an in-game contest running through January 11th, 2011. Players are tasked with finding seven Linux Steles scattered around the world and answering their riddles, with a ZaReason Linux Terra-HD netbook (or cash equivalent) as a grand prize for entrants. Whether or not you intend to start playing Ryzom on Linux, it's a nice prize and an excellent incentive for players to celebrate the new release.
