This will never be brought here, unless someone talked some sense to Yves Guillemot who is paranoid over DRM keeps bankrupting him. Oh well. If you played this on Steam, you might experience loads of s#!t from it's variety of bugs, which GOG could remedy. Also, having played it's PS2 version, I never get to experience it's original PC release from Red Storm.
Why they added the game to Epic first is likely the results of Unreal Engine 2 being used.
