Can this game be played with mouse/keyboard?
There are some adapters out there, I almost went with one. Instead however I went with this;

I do like it. There is a sniping button that slows down the reticle speed too, to make it easier to hit targets. However, not all games allow you to change buttons. In Overwatch I can change buttons in-game to whatever I want (buttons on the setup are hard bound, but using in game options you can change). I want right mouse to be jump, I have always used that, I can in Overwatch. In BF1 you cant change any damn button, its very annoying. I want the side button to be zoom, again I can do this in Overwatch but not BF1. In this game, there are some required tough shots to make, like certain parts of the Dinos. You can change the reticle speed with a button press too which helps. Much easier with this than a gamepad.
As far as the game goes, I am enjoying it. Its very open world. You can level certain aspects of Aloy, craft and build things such as arrows. I do like how you can play as you wish. You can go do certain aspects of the game before you should, you will get killed pretty fast if you aren't the right level with the right gear. Graphically it is gorgeous. Maybe a tick above Uncharted 4, but not by much. They both have huge outside worlds that showcase the graphics. Playing on a PS4 Pro, with a LG 65" OLED with HDR so probably about as good as it can look. The story is ok as well, nothing ground breaking but still unique. I would say anyone with a PS4 and enjoys open world RPG'ish games to get it.
