Tales of Unity is quite the intriguing tale. It features a lot of visually appealing girls, a fantasy world bigoted against humans, and compelling mysteries that unravel as you continue along. The plot is perhaps one of the most notable parts, Strokboi has created a very intriguing world. You get a lot of choices and player agency. Overall this is a VN I can imagine many enjoying.
Sadly, there are quite a few flaws that prevent me from praising the game more. While I don't expect perfect English, this is a game that has been going for over a year and has had time to have its grammar fixed up. Sentence structure is frequently confusing, hitting many of the aforementioned choices often led to me asking myself what the choices even meant. A curse of creating a game that is extremely text heavy is that it is an important aspect of the game; someone with broken English just will not be as enjoyable as someone who can write more fluently. YMMV here.
Another major issue of the game is pacing. While it could perhaps be praised for constantly moving forward, a big problem I find is that everything feels horribly rushed. Scenes often were a few text lines at best, often feeling like a brief summary. Context was always there, so I never felt disoriented, but it lacked a certain professionalism seen in higher end visual novels.
Choices were frequent, but the confusing thing about ToU is that it usually came down to "have romantic interactions or skip the scene". Note the latter choice would punish you later by giving you less information; the game is based around your closeness to those around you and thus essentially achieving the harem route. Polygamy is promoted and there is a succubus, so pretty much romance everyone, as the only real alternative is getting less information and thus plot. Now there are true choices in this such as dating the goblin or the wood elf, but far too often is there a "don't do anything" or "improve rating" as your two choices with each giving obvious results. There is a good/evil system as well, though I am not sure it has been developed to the point it really matters much.
Overall this is a pretty decent VN and definitely one that offers a little more than just porn. It is curious to see where the plot goes. It just feels like the execution itself could be better. Essentially, this is a porn VN with an above average plot; it isn't going to be a VN that plays with your emotions nor will it change your worldview in a groundbreaking fashion.
There is definitely some good humor in here. Strokboi has a nice style and knows how to not take things seriously, the end of chapter discussions are some of the better parts.
The choices feel confusing and almost worthless, the pacing is too quick for my liking, and so this feels like a game with a good plot that I am reading a summary of on Sparknotes. Tales of Unity is good for what it tries to do and it certainly has its merits for playing, the plot especially is worth checking out, but the execution just feels lackluster after being spoiled by better works.
