I've recently finished this and going for the platinum, really enjoyed everything about it, looks especially awesome in 4k HDR on an OLED.
Really enjoyed the story and setting too, but...
The post credits scene was a little weird, not really sure how that was possible
Weird, how?
So I'm not far in (only just got to the daytower) anyway, when you override machines do they only stay in the area they were patrolling or do they follow you across the map?
Ive finished the main campaign and frozen wilds. TBh i really enjoyed it, especially going thought he main missions of the main game and working out what had happened to the world.
You should get a Switch and play Zelda and Mario
I was going to say just wait until he plays Zelda if HZD impressed him.
