Why do Unity games have so many bugs?

Question

C++ / C#

The Unity engine is rumored to be appreciated for being fairly easy to learn and providing a good feature set.
But as far as I remember all the games made on this engine - online digger, blockade, battles and other VKontakte shooters, and the same popular Rust if you take it - they all have partial problems with optimization, bugs with textures, etc.
What is it from? Are developers doing a bad job on games or is Unity itself a bad engine?
PS: How good is UE in your opinion, is it good on mobile platforms relative to Unity?
Can Godot be better than Unity in terms of game quality?

Answer 1

Because Unity is easy to learn. Nowadays, even schoolchildren can easily start making games with Unity. Thus, games can be made even by non-programmers (not real programmers).
The second reason is the savings in development. Unity is already an economical solution in itself. Much is available out of the box. Specialists are cheap. At least cheaper than serious bearded C++ programmers. But you can go further and save on testing, on creating documentation, etc. Hence the buggy.
Well, the third point is various oddities and some through-the-ass use of Unity (not everywhere and not always, of course). That is, this is a lack of experience and knowledge about Unity itself, about its diseases.

Answer 2

Probably because the entry threshold is low.
C and C++ simply cut off the pioneers IMHO

Answer 3

Weird answers here.
Because fixing many bugs is not profitable after a certain limit. In almost any type of projects, not only in games.
If the bug is minor and complex, then it is more profitable to direct the same efforts to new features.
Such bugs are rarely fixed and usually along with something else.

Answer 4

Unity is a set of ready-made tools (like a screwdriver, hammer, etc.).
If there is no understanding of the operation of the tool itself , the principle of operation of this tool, all its capabilities, settings, usage patterns (and all this comes ONLY WITH PERSONAL WORK: docks, brain, experience) - you will never get a quality product .
