Whether you're writing poetry, making a game, or painting a picture, the actual value of what you create depends nothing on how you made it. It depends on what your audience sees in it (with or without influence from your marketing efforts). Even a painting made of pure gold wouldn't be worth as much as the Mona Lisa, made of paint on canvas.
With that said, MY perceived value of someone's Unity game is my own, based off of my own personal life experiences and whathaveyou. Being a game developer myself, I recognize the sheer amount of effort that goes into releasing a game. However, I am also able to recognize a lack of effort on someone's part when they do release a game, whether it is made in Unity or from scratch.
When I see a shallow Unity game released, and, worse, being SOLD for real money to real people, I get annoyed. Why? Because as technically impressive as it may be thanks to Unity,
a game is not code. Unity is there so you can realize your ideas without having to waste time writing a bunch of code that other people already wrote. So what I ask myself when judging the value of a Unity game is:
What did this developer add ABOVE what Unity already provided for him?
If the game had shitty art, shitty audio, shitty writing, and shitty ideas, then it is a shitty game to me. Even if it does have amazing special effects, physics, and assets the dev pulled off the marketplace, if they weren't able to add anything original themselves that wasn't shitty, then their effort was shit, and their game is shitty. If other people are content paying money for such a low effort, that's their business.
Also,
Writers rarely have a detailed, meticulous, academic knowledge of linguistics and etymology, and if they do it often makes their books worse (Tolkien, for example)
I'm going to pretend I didn't read that
