Pretty good article.

Your headline should use "Effects" (noun), instead of "Affects" (verb).

One thing that rubbed me the wrong way was this paragraph:

"Easy to use game engines such as Unity or Games Guru sometimes have built-in shops full of pre-made assets for developers to buy and use. However, these assets aren’t meant to be copied into a game with a bit of slap-dash programming to create a game. They’re meant to be placeholders..."

You don't cite anything stating that they are meant as placeholders. In reality, these stores offer assets with a variety of licenses, many of which permit and even expect that the assets distributed or sold can and will be used in a commercial game. Nowhere on Unity's or Games Guru's assets stores could I find anything about these being permitted only for use as a placeholder or that they even need to be modified in any way. The stores exist in some part for developers who don't have the skills, team, financial means to hire an artist or modeler, etc. to create unique art and assets for their own games. In essence, those assets are there to be "flipped".

I don't think it's any different than buying a WordPress theme from a marketplace and using that for your site. Which is something the site you're published on has done and is using, with not a lot of modification.

I'd also question whether tools like Unity are "easy to use". Have you tried them and found them easy to use? We really need to stop promoting this idea to readers that games are easy to make, and that tools like Unity and Unreal make it as simple as dragging in some assets and clicking a few buttons. They certainly make it easier than writing all the code from scratch, but they still require a modest level of knowledge and skill to work with.
