Oh, with Linux you can play old games(and indie games) and comfort you thinking that linux is the best platform for a gamer and 2015 is not old in the videogame world, meanwhile, your friends play Horizon Zero Dawn in PS4 or last FIFA 18 in Windows 10.
Really do you think that a gamer will change windows 10 for linux for play ancient games and cannot play the last AAA games?.
Finally, i have games how L4D2 in Linux, but if i want to play games how GTA or Asssasins Creed i need windows.
