Mate, Stephen Hawking was one of the smartest people on the planet, and I bet he preferred turn based over starcraft. Motor skills are not the same as strategic intelligence. Starcraft is a game with a solved meta, which prioritises motor skill over strategy. It's basically football as far as the intellectual difficulty goes.
And I say this as someone whose favourite strategy game is starcraft. Not because I think it's a well designed game, but because the Zerg are sexy and I want to fuck a hydralisk.
You can play Helldivers on a mobile data connection. And besides, Steam is there.
Also lmao most of Australia, by landmass, is only phones or no internet at all. But PSN is in Australia.
