When I check my game library on steam days ago, I found that Bioshock Infinite had landed on Linux too. However, there are data packs only, we still need to wait for the binary executable.
2K published a lot of its games onto Linux this year, such as Borderlands series (Borderlands 1 excluded), Civilization V, and XCOM series. Unfortunately, Rockstar, the subsidiary under Take-Two Interactive, has no plan to port their Grand Theft Auto series to Linux. I will not call 2K as consciousness of industry (because their boss discriminates against China), however, I still want to raise a thumb for them.
A lot of Euramerican game vendors are porting their games to Linux this year (thanks to Valve), which is really a good news for game players such as me. Of course, we can never count on those Japanese vendors. They even sniff at PC/Windows platforms, and Linux is nothing at all in their eyes.
