My point is that Hearthstone is an objectively worse game than Counter-Strike is, in the same way tic-tac-toe is inferior to Chess in almost all respects. I'm not denying Hearthstone is fun, and makes a metric ton of money. I play it a reasonable amount and have spent money on it. But it's not a good game.

I don't see how providing a direct counter-example to an argument is 'generalising', but whatever.
