Dawn of War 4 developer King Art knows what you all really want: 'Overwhelmingly, it's singleplayer content and the campaign'

It is.

I hope they're right! I seem to remember RTS games like Grey Goo coming out in the 2010s with a similar focus, and then not doing selling so well.

I really want a classic RTS with base building like DoW1 not the hero based 'action rpgs' that followed.
