Unity editor requires less hardware to run.
It’s a lot cheaper for institutions; some are beginning to use Godot because it’s even lighter than Unity.
But if one is really “serious” about game programming as a career then the best thing to do would be a bachelor’s degree in computer science and develop your own DirectX little game engine before you go job hunting.
If one can’t do that, gather 10 years experience somehow, publish games, publish things.
A course teaching how to press buttons on game engines will have almost no impact on landing a job.
Many Unity devs land jobs, it isn’t because they know Unity. It’s because they pick their iPhones, launch a bunch iOS games and tell HR: “-I built that.”
It’s proven experience, proven ability to commitment.
Unless all you did was “asset flip” and copy tutorial scripts, in that case after a few practical exames you’re out…
“Certification” that Unity is selling is only useful for them to grab more money from you and for the wild-west called internet.
Anyway, there’s hundreds of thousands of Indians and Russians “selling scripts” for $10, drastically reducing your value as a “Unity C# developer” after you’ve paid so much for these “game programming courses”.
