Arch Linux users can now install Castle Game Engine from AUR (Arch User Repository).

The package is available on https://aur.archlinux.org/packages/castle-engine-git/ . Follow the standard AUR installation process:

• Do it manually following AUR docs, like
  wget https://aur.archlinux.org/cgit/aur.git/snapshot/castle-engine-git.tar.gz tar xzvf castle-engine-git.tar.gz cd castle-engine-git/ makepkg -sri

  1 2 3 4

  wget https://aur.archlinux.org/cgit/aur.git/snapshot/castle-engine-git.tar.gz tar xzvf castle-engine-git.tar.gz cd castle-engine-git/ makepkg -sri

• Or use a helper like paru. Once you have it working, just use paru -S castle-engine-git.

Thanks go to Kagamma (Trung Le) for doing this!
