Saw the game featured in some of the disc servers I'm in, and gave it a shot.
First off - I'm surprised that the premise of manager of an Idol/popstar group is relatively rare among AVNs...
Anyhow, it was a nice start, but it's much too soon for me to have a solid take on it. Looking promising though, and I liked almost everything.
My main criticism is that the dialogs can be very rambly and yappy at times, going in circles too much. Two instances in particular stood out for me: the talk with the best friend in the KBBQ and the first meeting with Ruby where she and the MC start talking about gaming. There are a couple other instances, but those two were the ones that really made me think "can we move on already?"
Those two instances in particular could've had 60 to 70% of the dialog cut with no loss at all to the game or character development.
In instance 1, the friend wants to catch up with the MC and offer him a job, but there's too much parallel talk with the friend and in instance 2 we want to learn that Ruby is a bit of a rulebreaker (what with sneaking out anon at times), super chill and very cool gamer girl, but the characters geeking out on each other's gaming knowledge/habits could've stopped at super smash bros - we already get the point there. But there's a lot of talk of League, Apex, specific characters in all the games and internal mechanics of each game (like the sweet spot for Roy vs Marth) that is just INSANELY boring to read unless the player themselves is also having a nerdgasm over those things.
Comparing the dialog interaction in those two cases with every other character introduction would hopefully make what I mean crystal clear. All other interactions have much better, more focused and interesting executions. We got the sense that Tiffany is very shy and reserved, that Beaumont is a very blunt straightshooter who's also a bit of a fitness freak, Eva is an adorable clumsy ball of energy... See what I mean?
The characters so far all seem very likeable and distinct, each with strong (different) foundations from the get-go and that's awesome.
I want to see what the next update brings already, and hope it drops soon (though the game literally just launched, so it might be a while).
