You should go into Nier: Automata thinking it’s a game about a hot chick fighting a bunch of robots. The only spoiler you should know is that the end isn’t the end, and you need to play it again.

You should go into Spec Ops: the Line thinking it’s a game about a cool special forces team fighting a bunch of terrorists or something. The only spoiler you should know is that it’s supposed to feel like a generic third person shooter.
