Wow, many thanks for detailed answer! This is very usefull post about Real
Valley! Under "MultiMedia engine" I mean library/framework/engine for making
visual crossplatform application, who can be rendered to opengl/directx/webgl,
something like a [Kha](https://forum.nim-lang.org/kha.tech),
[OpenFL](https://forum.nim-lang.org/openfl.org) or
[NME](https://github.com/haxenme/nme) for Haxe. Probably, Godot and Nuclear is
it. Nim have a really impressive stuff and a lot of bindings for mainstream
GUI-frameworks, cool!
