The constant theme across almost all of these reviews is that the gameplay can be tedious, boring, and frustrating yet they are scoring it at an 8 or higher. So I think the real question this game is presenting is does a game have to be fun in order to be good? I would say in any other medium the answer to this question is no but games are different.
What does ERA think of this? Do games have to be fun to be good?
No. Some of my favorite games were not "fun" in the conventional sense, but rather they drew me in and kept me immersed in the world. For example, Planescape Torment's gameplay was mediocre enough that it was best avoided when possible, but the writing is what made that game a classic as it kept players intrigued and captivated. From last year we had RDR2, which was best outside of its linear shoot-bang mission gameplay.
