Rocks'n'Diamonds

So, it works like this: you create and write an .rulend file ( rule and diamonds , for short ) inside RnD , and it will create an game engine for it, based on your input.

Are you serious?

What would work: You create and write a .c file inside the R'n'D source directory, and the compiler will create a game engine from it, based on your input.

No, I mean, "You create and write a .rulend ( which a dedicated programming language for making custom engine for RND ) file inside the built-in R'n'D rulend compiler, and the compiler will create a game engine from it, based on your input".

I did understand you correectly, I was just being a little ironic.

No, there will be no meta game engine able to interpret rule files to create custom game engines from it (unless somebody takes the game's source code and writes one, which is of course always possible).

However, if you are interested in creating a custom game engine in R'n'D (maybe to implement some new "tile-based game" idea), I have good news for you! Just use custom elements and start today!
