Why is Unity the most popular engine?

But hey…you can spend $75 on the Asset store to fill that hole for you…and then spend HOURS learning the unique workflow of that Asset…and more HOURS refactoring your code to work properly with that Asset.

Unity made Demos often require $300-$500+ in Asset store plugins UP FRONT. How can you stand by an engine when they cannot even produce competitive tech demos without heavily leaning on the Asset store. $300-500 per seat for Assets up front is not “Free”

I agree, you spend quickly 500$ to try to close the gaps, and it becomes a mess of plugins that you got to manage, sometimes you have plugins not working well with others. Because it is not in engine it results of thousand scripts that will only slow down your game.
In the other hand Unreal 4 keep adding features to the engine each release , unlike Unity where you need to spend 50$ or 100$ each time something new is interesting and not in the engine.
