Catventurer: My biggest issue with this is that this looks like it was made with RPG Maker, which is my absolute least liked game engine. I've yet to play anything made with it that I actually enjoyed. I really do wish that if GOG is going to release more perv games that they'd at least release perv games made with something other than RPG Maker.
Darvond: Most Kagura Games publications are
[DULL SURPRISE!] made in RPG Maker; endemically.
Fallen Makina and the City of Ruins? RPG Maker, and obviously so.
Treasure Hunter Claire? Not even barely disguised.
Leanna's Slice of Life? They don't even box in the interiors correctly. Yes.
Detective Girl of the Steam City? Vaguely disguised, falls apart in outdoor scenes and menus.
Ideology in Friction? Couldn't even bother to switch from a default typeface or menus.
Chevalier Historie? Surprise! It might be RPGmaker adjacent, but I don't recall action RPGs being possible.
Kamikaze Kommittee Ouka 2? Yep. Though the dev did actually put some flourish on it.
The Heart of Darkness? Yes. One of the screenshots gives it away, but they tried to disguise it.
The Demon Lord is New in Town! ? Probably not. Looks more like Ren'Py.
Magical Girl Celesphonia? Yes, and there's a pretty obvious drop in asset quality between game modes.
The Imperial Gatekeeper? Yes, but they go to great lengths to hide it. The assets are a dead ringer.
Sonia and the Hypnotic City? Yep. The city's tileset poorly melds into a natural cohesive artstyle.
The Dead End? Yes, but they splurged a little on features.
Noelle Does Her Best!? Obviously. Doesn't even star a reindeer from a surface town. More baffling, the pixel art used on these characters. It's bright and colorful, but clashes with the rest of the Kaguro catalogue.
Succubus x Saint? Pretty sure, but could be engine adjacent.
Magna Fortuna? Yes, and they don't even try to hide the tileset.
Kung Fu Grand King? Yes, and worse still, I can't tell if the screenshots are the game window or not. Weirdly, the characters sport a pixel art style in game, which clashes with the ultra-anime portraits.
Apostle: Rebellion? No. It's also the nearest thing in the Kagonza's catalogue that
almost doesn't look like trash.
Castaway of the Ardusta Sea? Yes. Battle menus give it away.
Knights of Messiah? Yes. Menu typefaces give it away.
Serafina and the Key to the Egg? Unsure. I was more distracted by the Saberface on display. (IE, they look like ripped off Type:Moon designs.) And how the quality jarringly changes for the guard. I'm thinking yes. (Shop menu.)
The Triumphant Return of Diabolos? Yeah. It's very obvious. They didn't even disguise the chest.
Dungeon Town? No. Too bad about the incompetent artstyle that reminds me of early Touhou doujins.
Ambrosia? Yep. Doesn't even try to disguise itself. The faded pupils are a nice alarming touch.
Lelie Navigation!? Shrug. If it is, they did a good job hiding it. Possibly engine adjacent.
Summer Memories? No. It actually looks competent.
Shame about that one review pointing out this might be shota. Fallen Makina and the City of Ruins? Default assets, thy name is Fallen Makina.
So yeah. A lot of the games they publish overwhelmingly use it or cheap premade assets which look damn well like it. Many of their overworld characters aren't even 8x16 in proportions; so even though many of them might have more colors than a SNES game, they end up looking worse.
Apostle: Rebellion almost doesn't look like trash? Are you here just trying to start shit now, mate? Look here. Some people happen to like these RPG Maker games and there have been several horror ones like The Witch's House, Ib and Mad Father which are praised in the genre. I get that you don't like these games, but you're starting to sound like a whiny keyboard warrior now and it's pathetic. Dial it back a little, you're starting to sound like a pretentious hipster elitist who thinks that "people have to only like what I like" and no one gets to disagree with you. I'm sick of it.
And some people like shota and loli as well. Keep in mind um... Cyberpunk Edgerunners and the loli character that I've seen ridiculous amounts of fan art from over the past few days. I truly wonder what skeletons you have to hide that you feel the necessity to do this moral grandstanding.
