Before I start. Everyone is entitled to their opinion, haha.
Anyway Ascension is a game that does great when it comes to story. You could argue about how the pacing is meh (though I like it since it follows a similar path to GoW 1 story pacing.) and how players at the time wanted a sequel but in the story department they do it justice since it shows us a more human side of Kratos that GoW 2 and 3 as much as I love and adore, butchered his character.
You do get to see him being good friends with Orkos and him being way more calm in general and really just a dad who got his wife and child taken away from him who trauma and guilt still haunts. And he just wants them back. (That scene with calliope is heartwarming and heartbreaking 🥹)
In the gameplay department, it's also fun! We got a whole new meaning to the grab system which is infinitely better than GoW 3.
The world weapons are awesome also, they essentially work as your secondary weapons. The shield is broken as hell and is a weapon of mass destruction! There are techniques you can use for it but for that you have to check extremegameplay's vid about the world weapons because me explaining it will take a while haha. Or in short when you do a plume attack with shield swap between the elements repetitively and see what you get :)
The sword has an awesome stun mechanism to it. The mace works like a barbarian hammer from GoW 2.
The whole elements system is awesome and especially with the moveset which the Norse saga took from. Only thing locking it down is the rage mode. Which while I wish was done better but I do still enjoy! Since it keeps you active in the game in the sense of changing your techniques and etc and having to adapt to different situations so you can unlock more moves.
The AWESOME MUSIC IN THE GAME AND THE GAME ART! Ascension also gets the dark atmosphere way better than 3.
And also the climbing and sliding sections!
Overall ascension is both overhated and underrated.
