Oh. So gaming on a mobile device has catches in order to justify hate. Gotcha. A phone is no different then game boys and the like. There is no reason why phones should be treated as evil just because. The switch is essentially a limited tablet. Phones can play fortnite and PUBG. There is no reason why they can't be made to play more games by more developers. The high end phones have enough power to do it.
Blizzard can and should branch out. It doesn't matter if they are first and foremost a PC gaming company. Stupid limits like that would have stopped Microsoft from making the Xbox. Or sony from making the playstation. And yet we have a OS company and a Radio company that produce the two leading consoles.
And none of that changes that Blizzard is already on the mobile platform with Hearthstone. To say they can't develop anymore games just because is down right dumb. So is Hearthstone a bad game? Is it bad for Blizzard?
