Gonna have to say,i respect your opinion,but I strongly disagree.
For your "complaint" about the story being unoriginal. Hate to break to you,but pretty much every story in human existence is in essence,unoriginal.Even the most iconic pieces of modern media(Like Lord of the Rings) had their inspiration from somewhere. I don't understand how that can be a point against the game in itself. Yes,the idea of virtual world is not new,but execution of an idea is what's more important. And I would say that Cari does a good job of that.
Not just how the base premise allows for a variety of story genres to to be in one VN,without it feeling jarring,he also does enough to expand on the consequences, good and bad of Eternum existing. Like how because of the in game currency having RL monetary value, some people actually made their living in the game. Which helps in worldbuilding and making it feel lived in. Or how like in any social game,there are assholes doing screwed up shit.
For gameplay...really? Saying that there's little to no gameplay in an adult visual NOVEL. The whole point of a VN is to experience it for the story and dialogue. I don't know if you're just trying to note it for the review(even then it still feels kind of pointless to mention that) or if you really expected to go in having this be gameplay-heavy. If it's the latter then that's on you for expecting the game to be something it's not when Cari clearly labels the game. Cari knows what his focus should be on and any tiny bit of mechanics are there to serve the story and atmosphere,which works out great especially in the horror focused sections. Any fleshed out mechanics would not serve the story Cari's telling and just take away time and attention. And the choices to me have the right amount of agency. Not too cryptic that you have to depend on a guide to get through(although that first Alex choice is an exception),but inuitive enough that if you pay attention to the character's personalities it's pretty easy to pick the right choices. And wanting the girls to be harder to woo..can't say anything against that,but I also don't agree with that.
And for the characters being "copy-paste" and "sex-crazed". I really can't agree with you here. Out of all of the sections,this is the one that felt the most disingenuous and overblown. Putting aside the fact that this is at the end of the day a porn game,one with way more plot than porn,but still a porn game,so dinging it for having some "porn logic" is really?
Having "unoriginal" characters is not,IMO a valid criticism.I can just put my same thoughts about that from the story section. Yeah, the basic archetypes are nothing new for AVN or general stories,but Cari's writing does a good job of fleshing them out beyond that,especially in the emotional scenes to make them feel believable. And speaking of that,I also think Cari for the most part does a good job of not only properly pacing the sexy scenes to their relationship growth with Orion,but having good in-character reasons for why they chose to do it. Nancy goes faster than the other girls,but that makes sense because of her bolder personality and how repressed she is than either Alex or Luna who took longer to get their first sexy scene. And the times they don't are more the execption than the rule like you seem to think it is.
And feel like the only one that maybe fits that description is Dalia as I'm not a fan of how you start her path and later on with the bet,but that's more due to the timing,but other than those,her path is fine. I don't know how,when you talked about the different dialogue,animations,and the focus scenes for each girl,you still came to the conclusion that,nah, they're just copy-pasted sex dolls of each other,which made me roll my eyes. Apparently I didn't play the same game you did.
So yeah,I think this is overblown.As for Orion while his basic personality traits are typical of the AVN MC,Cari's writing makes Orion feel a lot more genuine and fleshed out. Orion may not be Cam (TFTUV) in terms of a defined personality with flaws and arc,but he still has enough character that I want to root for him.
You review starts off alright,but towards the end in the character section,it's goes straight into pure nitpicking for stuff you personally dislike and not objectively rating the game for the stuff it's trying to do. If you want to convince people your review is constructive criticism,maybe next time don't word it in a passive-aggressive way and blame others for not liking that.
