I'm (still) playing this, just started working towards ending C. I get the praise for the game, I do, but I do find it a tad... boring to play? The world is bland, the combat is a bit dull (I know, I might not have explored it thoroughly as I play on Normal), and while the story seems interesting, I think it has been dragged too far out with me having to play the same game twice to uncover the true story. I get it, it's a way only games would be able to tell a story but I think the revelations in 9S' story were... too weak.
I will finish it, though, as I am curious as to what the heck is going on.
