Unless counting Tux Racer, SNOW is one of the first winter racing games available natively for Linux. The Linux support was added for this week's open beta alongside the Windows support, which had been available since 2013. Interestingly, this free-to-play game is powered by CryENGINE.
The SNOW 0.7 change-log mentions, "Added Linux support - still work in progress, but should run decently." There are also many other improvements as part of the v0.7 release.
Those wishing to learn more about this winter skiing/snowboarding game for Linux can find additional details via Steam or SnowTheGame.com.
