There's absolutely no chance I'm playing that game on my steam account lol, but I actually really enjoy Artificial Academy 2 so I'm writing one anyway
I don't actually see a lot of Japanese games on this sub, I assume because it's stupid difficult to set up, and also more distinctly illegal to obtain for most of us
Anyway, AA2, for anyone who doesn't know, is basically a sandbox school life dating sim.
TL;DR: Putting this up here cause this is much fucking longer than I expected it to be lol. You make characters in a pretty damn good character creation system, put them all in a school together, and the AI all plays the game the same way the player plays the game with a few very minor exceptions. You can build whatever experience you're looking for by making characters that fit what you want out of the game. You could go full dating sim and focus on one girl, or make a school of sluts that are having orgies all the time
There's also a pretty solid modding community for a lot of aspects of the game
The thing about this game that makes me like it more than any other game, though, is that every NPC is fully autonomous and plays the game the same way the player does.
The character creation is great in terms of visuals. There's not enough body sliders, but there's enough hairs and stuff to make everyone look unique and good looking. You can always mod in more if you want, too.
The important part of character creation to me, though, is the personality. There's base personalities that decide their dialogue and voice and stuff, but there's also stats for sociability, virtue (sluttiness), and stuff like that.
Then there's traits, which are things like:
Chatty - More likely to approach other characters
Class prez - Spends more time studying, less likely to skip class or fuck a teacher, etc
Always hungry - Can eat as many times during a period as they want, where most characters can only eat once
Sweaty - Shinier body, spends more time in the showers
Competitive - Goes out of their way to interrupt conversations with characters they're interested in and start competitions
Evil - Can rape and/or murder other characters. I'm not into this but I know this would be a deal maker/breaker for a lot of you. You could easily choose to put it on as many or as few characters as you want
Etc. Traits all change how characters behave in the sandbox and how they make their decisions. There's 25 characters in each game, including yourself, so it actually creates an interesting variety between them and it's not just a horde of samey NPCs all working towards the same goals. There ends up being characters you barely notice because they keep to themselves, and characters that always seem to be in the middle of everything
I just really enjoy watching the AI run around and having friend/lover groups form organically over time
The school aspects are pretty basic. You go to school every day except Sundays and just hang out in the hallways basically, the gameplay takes place between classes with just a minor "how hard do you wanna work on this class today?" choice for 3 classes a day. You can completely ignore all of the school aspects of the game if you want to, there's very little downside and no punishments
You don't have grades, but you and every other character do have class ranks based on how much you've studied and how well you do in classes. There's certain personalities and traits that will make characters work harder at this, and be more friendly towards people ranked highly or above themselves.
The most impactful thing about the school aspect is that there's a test every 3 weeks in one subject, and your grade is dependent on your rank. The reason this kind of matters is because some characters will "encourage" you to do well on your tests by offering sex as a reward for good grades
Talking to characters is done through a dialogue menu that's basically just a choice between being friendly, flirty, or mean, and then specific ways to do each. You build relationships with characters based on a combination of Like, Love, Dislike, and Hate points, which all add up to a unique relationship status. For example you could have someone be super into you sexually but you're always a dickhead to them, so you get "Hate but love". Just a little bit of like and love makes "I think I like them..."
There's also some unique modifiers. Evil characters will have a special relationship status with someone they're planning on killing. The teacher has their own unique relationships based on that points system. Relationships are modified by if you're dating. You can get "Fuck buddies" if you have sex without any love points, or "Hole brothers/rod sisters" if you're both fucking the same person. Rape will also, obviously, change your relationship with someone pretty drastically.
As I said already, you go to school every day except for Sundays. There's 4 time periods each day, and the time is measured by the amount of interactions you have during it (it's a lot, it doesn't feel restrictive). Between each block of time is a class. Each block is also slightly unique in terms of things you can do, but mostly the same.
Before class, characters filter in from home over time, and some will never show up until class starts meaning they aren't available at all during the first time period.
The second period is before gym/swimming depending on what day it is, which means everyone goes to the locker room to change. You can also have a snack break or something during this period with anyone who wants to go with you. Some characters, mainly lazy ones, will sleep through this period in the classroom
Third period is lunch time and before clubs. When you're filling your class with characters at the start, you assign them all a club which will be the one they go to after this period. Some give different benefits over others, but it's all related to grades so it actually mainly just matters for being in a club with a character you want to be able to talk to more
Last period is after school, characters will slowly filter out and go home. There will always be at least a few left hanging around so you never end up by yourself, though. You can also invite other characters to your house to "study," which, depending on your relationship, can either mean study or sex
It's an anime tiddy game there has to be sex. This is what everyone here is here for. The sex is pretty basic, you choose a pose and watch it for however long you want, and every character has preferences for which positions they like. I say it's basic, but I would say that about basically every sex part of any game. There's not much you can do to make sex special without turning it into a burden for one handed play
You can technically have threesomes, but it's complicated and not animated. It's just some dialogue and then a fade to black with some moans
NPCs will have sex with each other autonomously, and often in places where you can find them. You can watch them, but it's just the low poly versions of them having sex in the overworld, not the fancy graphics sex scenes. Other NPCs who find people having sex will sometimes masturbate while watching them. Or sometimes they'll just masturbate when they feel like it. Sometimes you'll get special dialogue with characters for watching them have sex or masturbate
Getting to the sex portion is different depending on the character's personality. Some characters have a chance to accept a public sex proposition as the very first interaction with them, and some will absolutely never have sex with you unless you're dating and have been on dates with them, and then only in private at your house or a hotel
