There is two biggest problems with this game
> low difficulty, you need to gimp yourself or avoid playing parts of the game to actually have some challenge, there is tons of resources, characters and stuff laying around - zero scarcity
> no replay ability/no NG+ content, you can recruit everyione in one run, choices are very limited/mean nothing, no different paths or endings
The only ''missable'' character so far are people who you execute/refuse and Melisandre(that have some conditions to be recruited)
And don't get me wrong, I like it, its very enjoyable, its just half done in terms of gameplay
