That's the problem if the the feature that is given an assessement isn't properly stated.Shallow?!
I don't play it for the shiny bait. I already have everything. I play it for the depth of the combat. I use all 14 weapon types. If you're getting bored then you're probably the repetitive one sticking to a single weapon and build.
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.
