How many of your games run on Linux?

Jonathan MathewsPublic

Gamer? Check. Linux user? Check. For years, one of the top excuses I heard from friends who would otherwise have switched to Linux long ago is that they just couldn’t give up their Windows-only games. I can empathize.

Manned submarines and many automated subs can surface to communicate over the air, where the bandwidth is … Read More
