ratchet, why are you oftentimes so negative? Try to create such a scene yourself (with or even without the gameplay) and you will see how hard it is. Why the comparison with a mobile game again and why do you tell us/ him that "the engine does not count too much"? How is that relevant?
Additionally, when your opinion does not matter why do you post it then? And please don't call every second thing (shader/ some system/ component), contribution or not, "useless", I really hate to see that word.
