I agree that the game is ambitious but it also does a bunch of stupid decisions. The majority of the quests are pretty insignificant and only serve to make the game much longer than it should be, especially when the game already has a good amount of content. And for a NTR game, especially of this level, the scenes are pretty good and I do go back to them but it really misses out on a lot of potential NTR. The dude who's mind controlling the red haired chick keeps on talking about what he's gonna do to your partner and never actually attempts anything. There's also that dude from the same village that went out to be a knight before you. He starts off sounding like he's aiming for your girl but by the end of the game, he's turned into a rival character and while he gets a bit of character, he falls pretty flat. Even worse is that he has a bunch of moments that feels like its building up the NTR then nothing happens.
I kinda feel like the developer's priorities were pretty backwards in making the game. Not saying the game is bad, far from it, but missed potential is missed potential.
