First off, I usually don't play "Western" H-Games. Ironic to even call em that, since VNs were not "Western" orignally, but as time went on in the H-Game world, it seemed that most Japanese devs (if not all) shifted away from VN style games. At least when it comes to H-Content. To make it simple, I normally am interested in RPGM games, 2D Sidescrollers, SLG etc.
With that out of the way, the writing and wittiness of Corrupted Kingdoms is impeccable and unmatched, when comparing it to Asian games
Tons of effort has been put into the script, the story, and character personalities. It's just extremely charming all around with different archetypes and an almost wacky but interesting plot. 10/10
However, when you put such an incredible amount of effort into the script, other aspects need to suffer and that is mainly the H-Scenes in my opinion. The entire game is basically pre-rendered (I am 99,9% certain Koikatu was used for this) and you are merely watching a movie file being played. This means you have very little freedom of choice once a scene has started and there's just little variation overall. Also, the rendering seems to have quite a lot of artifacts, at least at 1080P resolution.
This sounds like I am bashing the game, but like I said earlier, the writing, dialogue, story, and characters all make up for it. But If extensive H-Scenes are a dealbreaker for you, then you should probably skip this one.
The person (group?) who is behind this project, really has some talent for witty and funny writing, so making this game a VN was probably the best idea. On the other hand, I am 100% sure that ArcGames (whoever you may be) could shoot for something bigger if they shifted away from the VN style, but that's just me.
Thanks for reading my twitch chat essay.
