So, I bought and tested rpgm unite so you folks don't have to.
First for folks who doesn't know what is it. RPG maker is an engine which used for most of your favorite spanking games here like SpankQuest, SpankingFantasy, Infused... you get the idea. Recently new version of this engine is came out, which is integrated with professional engine for game maker - Unity. Newer is usually better so I checked if it's any good.
Here is a quick summary and then I'll talk a bit more in details:
Cons:
It's not that straightforward as older rpgm versions.
Making character sprites is pain in the ass.
None of actual previous issues of rpgm engine was resolved
Pros:
Full HD resolution
No limit on tile size or number of frames in animation.
Sourse code is open and plugins are easy to build.
So, after couple of hours of installing rpgm unite then unity hub then unity editor then deliting unity editor and installing from archive old but supported version I opened premade project to see how it's all done. And well, UI is nothing like common rpgm. It's not THAT bad if you know unity or watch an hour of online manuals, just note that if you think you know rpgm and can handle that easy - you don't. Everything is in the wrong place and gosh it's hard to find. But when you make a test run it started in 1920x1080 resolution. All old textures are remade to full HD. Finally, good quality arts can be inserted in rpgm!
I get the common idea how to make something which can be called game after two bottles of vodka. And realized that I need to make characters! Back to fun hour of downloading. You need VRoid studio (yes, I feel like I can be Vtuber now. Much more profitable probably then making spanking games), couple of naugty texture packs for it (naked body is surprisingly hard to find), and fnally "RPG Maker 3D Character Converter" which is also cost money!!! Not much but still. It's easy after that, you made 3d model in Vroid, import it to converter, convert it to spritesheets and import them to Unite... then realize that you need to do that for all your 200 NPC and cry. I can probably find a way to make it quicker... probably.
So you get your engine and your characters. Then comes good part finally. You can use any image to load inside. No matter it's resolution. You can load floor backgroud and set up collisions. You can upload high resolution art of house and just plug it there. The result picture is so so sexy! The only issue is where to find it. I guess Unity asset store is the right answer but I'm not getting paid enough.
So next is plugins. First of all two things that was horrible in rpgm is variable management and localization. Well, they still the same. But at least now all of that actually can be changed by you... I mean me. Nobody else will use it am I right?

Sourse code is opened and if you know C# language which is pretty simple you can mess with the core of RPGM itself. You can change literally ANYTHING you can imagine and it's not that hard. My plans is to add proper variable store and method to grab text lines from resourse file to localize it properly.
So, to those who read all of this a have a treat. Here is my sample project made in RMU. There is nothing to do except going into hunting house. Enjoy new rpgm resolution! I'll make another update to this if I have time to continue poking this engine.

If it was any helpfull please write something back so I don't feel like I'm doing useless job. Thank you
