sonys version of monster hunter
That is too broad of a comparison really. You don't have to like Monster Hunter to enjoy Horizon. The only real similarities is the hunting of various "beasts", some incredibly large.
I personally don't like the Monster Hunter series much, and Horizon is one of my favorite games of all time. (although the MH creature art is fantastic, and watching skilled players take out huge beasts together is entertaining)
Watch a review or two of Horizon to get the jist of it. Has a great post apocalyptic story and main character/lore/world building. Combat is exciting but can get repetitive if you are not willing to try out the different weapons/tools that are slowly introduced to you. And as you get more skilled, you feel like you are becoming more the hunter than the prey.
Very large, open world but can feel a little empty at times if you are not willing to explore lore items/locations. Humans are the endangered species here, so it's not unusual to not meet many NPCs.
For all it's minor flaws, it was met with great praise and received many accolades, and Forbidden West is at the top of many gamers 2021 release lists.
Might not be your cup of tea, but at least check it out before dismissing it altogether.
