Pros:
- Lots of hot content that's fun and addictive to discover
- Returning cast of sexy characters w/ a couple of fun additions
- Adds useful features like stat tracking
- A better-balanced in-game economy than the original
Cons:
- Way overdoes the need for grinding
- Extremely abstruse paths to some achievements
- Cam-girl mini-game is just bad
- Billed as "finished" years ago but still isn't
In-Between:
- Way darker underlying themes than the original (might be a feature for some)
Overall, a solid follow-up to the original Chloe18. It's the MC that really makes these games work, a winning blend of sweet and naughty with an impressionable nature but a never-say-die attitude.
There are flaws, to be sure. There are plenty of points where you have to guess at a super-specific and unintuitive chain of actions the dev wants in order to progress. Also, without Chloe and some other great characters, one wonders if the grind-heavy gameplay would be worth it, and the cam-girl mini-game (an obnoxiously loud and visually distracting clickfest) is a rare case of GDS entirely missing that the point of a sex game is the sex.
All of that said, the game is still fun and addictive and Chloe's world a pleasure to explore. Some old favorite characters like Pizza Girl, Carrie and Hannah are back, and new characters like Taylor and Amy are fun (even if very little of Amy's story has been finished). There are useful new features like Chloe's notebook that tracks her stats and relationships, and money in the game is better balanced, neither radically scarce in the early game nor ridiculously abundant in the late game.
Be warned that the material is a lot darker, though. Chloe's original quest wasn't about shaming or bullying anyone, and she wasn't a dope fiend or a blackout drunk. Here, her major arc is about trying to publicly humiliate her "friend" Taylor in particular -- the game being unfinished, we never see that arc's outcome -- and there are whole story branches about substance abuse-related noncon. Basically, "Back to Class" Chloe is a worse person with the capacity to make worse choices and experience weirder shit than in the original game: whether that's a feature or a defect will depend on your personal kinks.
