About the goal of this engine

[Mirage]

Or if you are really interested in making engines, why not help me instead?

This question was asked by many developers including myself.
Seems that the answer is - no one interested to "help someone" with his engine/library.

This project was done over 8 years, so I ask, is there any point of doing an alternative from zero?

Not from zero. Most (if not all) of us has game development experience and even code which can be reused/adopted.
So we can perform well at least on start.
Also a team can work faster than a single person.

This should happen several years ago, but it's better later than never.

And finally, I ask, is there really a need for a full engine for pascal developers?

There is a demand on high-quality cross platform engines. No matter what language was used and even what language a game should be written on.
