All the tutorials and learning resources are hyper unity focused. That’s why so many game devs pick it up. That’s why they cornered the less than AAA industry. A young person will choose unity over the others for the same reason as they did last year. The endless resources to teach.
It’s likely almost all developers will pick unity for the next project too. All their knowledge is in unity, not Godot or unreal. We have this problem in other software industries too, some languages and frameworks are just better, but you can’t use them in your project because there are only five people in the industry that know how to use it well.
