I mean, adult content of whatever kind doesn't always have to be cheap smut. That's mostly what drives me to play these kind of games. There are enough braindead fuckfest "VN's" out there if you ask me.
If you liked Eva's first game thinking it had good routes, I don't see how this one suddenly is just a soap opera for you. It's a pretty similar experience (too similar at times for my taste even), and there's still lots of fucking.
Oh, and I have to absolutely disagree with your..uhm..tier-list? I can't play games with garbage story, just as I wouldn't want to read a book or watch a movie with garbage story. No real difference there, atleast not to me.
But hey, to each their own.
