i really don't know how anyone can be bored with HZD as it is non stop action and story - whereas GOW has barely any story or characters at all.
Probably in the same way that someone can think that GoW has no story. I mean there are a bunch of people in this thread saying the story is good in GoW and then there is you who says that GoW has no story and equally oddly, no characters, its almost like you barely got anywhere in GoW and are basing it off the first hour of the game or something.
I really wanted to like HZD because I heard so much about it but I tried, and I tried, and I tried, 4 times I started the game and each time I just got bored at around the same position (about 5 hours into the game). I liked the graphics, loved the premise of the setting, enjoyed the combat but something about it just simply didnt click with me and I ultimately each play attempt found myself wanting to play something else. I'm clearly not the only one who felt this way because of the 10,167 negative reviews on Steam for HZD there are quite a few people who say in said reviews that they found it boring.
GoW on the other hand gripped me and I didnt want to play anything else while I played it.
So the crux of it appears to just be that HZD clicked with you but GoW didnt and the exact opposite for me, GoW clicked with me but HZD didnt.
