Hard to say really without knowing what games you've already played, so a premise about what it includes is easier:
It's a college based visual novel where the split is probably about 35-40% sex scenes and the rest being story and freeroam. If it's afaik one of the first AVNs to have a college based theme, but already one of the best when it comes to models. Imo when episode 1 was released back in 2019 it had close to no games that came even close in graphics quality.
A few pros and cons imo:
Pros:
- Very good graphics ever since the beginning, especially considering when the first episode was released and it's been improving a bit to a lot with each episode.
- A large amount of girls to interact and have sex with, with pretty much all of them having a (close to) unique personality and a large variety of looks and ages (currently the oldest you can have sex with is if I should guess somewhere in her early to mid 40s)
- Extremely good and varied soundtrack, with the possibility to put songs in your favorite list so you'll only hear those unless a specific song is forced in a scene
- Pretty much all of the sex scenes are hot and well animated, definitely still among the best in the genre that I've seen.
- The humor is in general pretty on point, especially when Derek (becomes MC's best friend and "maggot brother" close to the start of the game) is the one causing it.
Cons:
- Four of the five main girls have big to massive breasts. Great if you like those, not so much if you prefer medium size or smaller.
- The freeroams (which are mandatory to do with episode 9 being almost one huge freeroam) can be quite clunky to navigate, especially in season 1 where you don't have fast travel yet.
- So far the story contains lots of tropes and the plotlines are all over the place. The very few plotlines that already have been resolved pretty much ended with a whimper.
- The dev time between current episodes is very long. The game isn't done yet, with episode 12 expected to be released somewhere between August and October this year. Next season will be the last and if episode 13 will take around the same dev time, it will probably again be about 1.75 year (although the dev has said that the last season will be different than the first three, but he hasn't mentioned yet what that exactly means).
Also this game/franchise takes a bit of inspiration from the Harry Potter franchise when it comes to atmosphere: The first two seasons are in general extremely light hearted and fun, but starting with season 3 there are more dark themes implemented as the game goes one, with episode 11 having a couple of very dark scenes. It hasn't gone as dark as the dev's previous game (Acting Lessons) yet though, but that might change in the last few episodes.
I highly recommend this game, it's placed somewhere in the 15-20th spot when it comes to my all time favorite AVNs.
