I’ve played Horizon and Nier Automata. HZD is the game with the most mass appeal so it’d probably be your safest bet. It’s not a perfect game, but might be my personal favorite this gen.
With Nier, you have to replay and beat the game a few times over to get the whole story. Gameplay is repetitive, story if you’re doing just one playthrough is forgettable. The game looks beautiful with a great soundtrack, but even despite that I’d say it’s far from a must-play game. I haven’t played Detroit or know much about it, but it seems like more of a niche game.
