[Review as of 0.20, the end of Ch2]
The Seven Realms is sprawling and ambitious, with a diverse cast of characters, a wide world, and solid visuals. At times it can sprawl a bit too much, but overall it boasts considerably higher quality than most of what you'll find on this site.
There's a lot to like about this VN. It's technically strong: the visuals are good, the English is solid, and there's nothing to really criticize about the basic execution. The characters are generally believable and the lore and story are intriguing. The choices feel meaningful without feeling infeasible for the developer: they largely impact character attitudes without impacting major story outcomes (at least thus far). They keep the game moving forward while giving you the opportunity to define how the MC feels about various important actors, perhaps even letting him be tricked in some of the intrigue going on.
The plot itself is generally compelling, but suffers from how overpowered the main cast is. You're never in any real doubt as to the outcome of any given encounter, and most of the tension in the story lies in navigating the MC's relationships with other characters rather than the actual situations at play. While this still works alright, it feels like a bit of a missed opportunity. In particular, I can't help but feel like the MC isn't really developing: I'm instead just selecting options that reflect who he already was at the start of the story.
The writing is at times a bit sterile. While it isn't clumsy, awkward, or outright bad like you'll often run across in amateur products, it never really quite lands for me either. I grade all VNs on a curve since they're all fundamentally hobby projects, but there are some that still really get me turning the next page, laughing along, or super invested in some of the characters. The Seven Realms kept me interested enough to finish it, but never quite captured my imagination in the way that the occasional VN does.
While the main cast is strong, likeable, and interesting, the supporting cast at times leaves something to be desired. In particular, a large number of women are introduced largely for the purpose of variety in sex scenes, broadly classed as the harem by the dev (neither core love interests nor one-off flings). While I understand the basic goal of bringing variety without overloading the core character count, I think it goes a bit too far in the other direction: this side cast appears enough to imply they'll get more content, yet rarely actually does. Either moving a few to explicit one-time flings or spending more time with them would be welcome salves.
Overall it isn't perfect, but the Seven Realms stands out as one of the stronger titles on f95 right now, and is easily worth a try if you're looking for something new to check out.
