That's the problem if the the feature that is given an assessement isn't properly stated.
You are refering to combat which appears to be deep. (I don't know the game so I can't judge.)
@Andrew23; most likely was talking about another feature like story and/or quest design.
So… you both could be right.
If a game is worth playing just depends on if the features that are important to a gamer are well done.
Ofcourse, combat is the strong point. But not just that, I would say that monster design is great and also level design is very fine. I enjoyed it, apparently, as its in my top 3 games in 2018 based only on time played according to Steam. But I consider it more of a guilty pleasure.
There are numerous options with regard to weapon sets and equipment. And each weapon set is different and plays in different way. So far so good. But. Looking on each weapon set alone, as soon as you get familiar with those few special attacks and mechanics each set has, you are there. Thats the end, its not evolving anyehere from that point. All you can do is upgrade the weapons or armor, making them more efficient. No more no less. Also the game itself is guiding you to use most efficient weapon as many hunts have to be finished in certain time limit. And making the weapons more efficient means upgrading it. And collecting upgrade materials, that is grind in its purest form. Ring closes, rinse and repeat. And when you finally get that upgrade you worked for, new one pops-up in front of you. Suppose its subjective, but for me that is not enough to call it deep experience.
