To be honest, the main story is so not gripping (outside of Kas) that at this point all i care about getting is a satisfying conclusion to Brienne's stuff and more mino village. Once those are done, i'll probably be done with the game.
I mean, i guess there are other nice characters and shit, but most either got abandoned before they could go anywhere (Clementine), shafted when they were getting somewhere (Azy and the mare-girls), or will get shafted (Ryn, and in all likelyhood Kas too).
Just, most of the decent stuff is too all over the place to give a shit about. Not as bad as TiTS, but i see it getting there.
