[ 2 ] I want, also, some way to build audio game engine tools, but Unreal4 or Unity 3D isn't work on linux at now, some suggest for my frustation ???

As otherwise noted Unity does have a linux build, I've used it to make a demostration game at work (see https://forum.unity.com/threads/unity-on-linux-release-notes-and-known-issues.350256/ ). Personally though I'd rather see more work be put toward the open source Godot engine (see https://godotengine.org/ or #godotengine on freenode).
