I'm gonna finish off dark souls remastered first and then enjoy a relaxing game. It's my own fault for trying this without finishing dark souls first haha.
I spent an insane amount unnecessarily doing everything and grinding in route A of Nier: Automata. The combat is engaging enough, while also not requiring you to be extremely focused. Made for a great game to listen to podcasts to. After all, there's a lot of places to explore, rewarding you with weapons and a lot of side quests you can get early. It was a game that didn't burn me out as a completionist.
It's also possible to just rush it as well, making things more intense. But the big maps with verticality and the great music made me just enjoy taking it slowly. So it all really depends on you as a player.
After you're done with route A, there's route B which takes control over another character during the events of route A, which overlaps a lot with route A. So some feel it a drag to play the same thing over again. I honestly enjoyed it though, especially because of how it gave a new perspective on route A. But that might make a case for rushing through either A or B. I personally grinded in both because I loved doing side quests and the combat just felt so great and just flowed with me. After that there's route C which is a whole new thing and is the last route of the game.
