VNs are games in the same way that a choose your own adventure book is a game. In some ways yes it sort of is, but in other ways it's something else. I'd argue that VNs require a lot more creative effort than a game does, because a game can get by on well designed mechanics.
Blender is pretty cool, I've been playing around with it since the 1st version released. I still script in RPGM MV occasionally, but I've been working more with Godot and Renpy lately. If you like VNs, I highly recommend giving Renpy a try.
Scripts don't just fix poor creativity, the lack of scripts just show a lack of coding prowess. Using scripts as a substitute for eventing is also dumb, and it's less necessary in MV than it was in previous versions of the engine, but it's still pretty necessary for anything you make as more than a hobby.
Making your own art is also technically optional, but most people aren't going to play a game that primarily uses the art that comes with the engine.
