World of Warplanes? Don't make me laugh.
War thunder is better.
Command and Conquer helped create the modern strategy game, I would say that makes the game relevant, and should have a spot on this list
I think the list is more "What is the most fun right now.", they say "Here are the 15 best strategy games that I think you should all play right now." I love command and conquer but I don't think it has aged as well as some other titles.
Nothing wrong with lists of the most important titles, I just don't think this is that kind of list.
