All amazing. God of War has such a wonderful moving story and great combat. Horizon Zero Dawn is an expansive open world game with also a great story. It also has a lot of additional info in discoverable content, like logs to read and sound clips. So, it depends on how deep you want to dive, but I’d recommend both those games. God of war is more challenging on higher difficulties. I loved them both. Probably Horizon Zero Dawn just a little better than God of War, but then, I loved God of War Ragnarok more than Horizon Forbidden West.
