Yes, now it's a waste of time, but considering the ntr routes were really go for a long time, endings are a big let down.
I just think that quality of this game dropped significantly at some point, excluding renders which improved a lot. Or maybe i'm just bored, i never liked Christine as a character, that's why i had a hope to see bad ending with her.
About new geme, yes it can be better on romance path, but i doubt about ntr. Looks like only wife wil gets this path and i absolutely don't give a fuck about her.
