Haven't played those yet, urgg i am traumatized by "chinesse" translations, i will chekc the first one and if its good (the translation i mean xD) i will probably buy the second.
They are ntr right? Not netorase, also harcore ntr?
I played through most of it, it is netori. The game got a pretty long time before you actually start doing anything. It is pretty much a dating sim, just that the wife is married. It is more pure love as well, as she is in an arranged marriage from what I understood and never really felt "love".
So do not expect degradation cheating like in NTR legend. There is netori play later in the game, so it is not barren, but definitely felt very vanilla.
Still a good game I guess, just did not understand why it was THAT highly rated, but after looking around more, these types of dating sims do really well rating-wise for some reason. I guess an interesting part is interactive sex scenes, where you gotta get her in the mood with some foreplay and then start moving further. You can choose which zones to focus on, which acts to do etc, so it is not on rails.
So overall, it is more rated for the dating sim part rather than the netori part imo (it just adds a bit of spice).
