The channel LinuxNativeGaming appeared on YouTube

While there are about 30 commercials of different genres, from Quake4 to Osmos, you can see a few minutes of live gameplay, evaluate the graphics, and more. As I understand it, the author is completely open to feedback, and at the same time he is clearly a slacker, so that he can not only make the review interesting to the game viewers, but also give recommendations on how to launch and debug in case of problems.
I find the service quite useful, because It’s better to see the live process once, than read reviews a hundred times and view trailers on the developers website.
