Mmm yeah, I mean KHUX has an auto battle system too and you can leave your device idle for a bit but it still requires some level of engagement (walking up to the next enemy, using your supernova attacks, paying attention to the enemy counter). I suppose you do have the option to turn off auto battle and play KHDR manually but even then it's still pretty hand holdy.
If the story is all this has going for it, then I kind of question if this was the best medium to present it in at this point. And I'm really not trying to rip on this game.
