The first company to release a descent MMO with a "Limited Action Set" on console that has truly cross platform servers is going to have huge success. Player numbers matter. I recognize the difficulty and hurdles, but it's something to consider.
That being said...everyone should be looking hard at Linux as their next platform of choice, for many reasons. Thanks for including the fast growing Linux community in your development plans!
I absolutely agree that consoles lack on MMOs, I can literally count them on one hand. Besides PC, I play on console too, and they have huge potential.
Linux and macOS never got the love they deserve from the Gaming side, and many people use them daily, so why not bring them aboard.
