there's... like no gameplay at all here, this is something below what would be called as easy.
you drunk buddy? in hentai games industry there are FAR more software that can easily create 2D games than 3D games. RPG games we have RPGMaker series, wolf RPG, both engine allow anyone to make RPG game even IF the said person almost have zero knowledge of programming, but dedicated individual can create a masterpiece with this engine alone.
no it's not, there's different between making a good looking 3D model and just making 3D model. i have tried several software that use to create 3D model graphic and it's NOT easy, it require serious skill to master the software alone and it require another skill or maybe talent for one to create a good graphic model. you can't just say that racing on F1 is easy to random people who only driving car to office everyday.
on the other hand, making 2D game is easier due to countless software allowing you make it, either the 2D graphic is just static like a CG on many RPG maker graphic or it have minimum movement using E-Mote or literally cut every single frame of said animation and render it inside the engine (Dieselmine also did this in their old works in RPG maker)
