I'm not 100% sure if Nintendo is gun shy about 3rd parties remastering their games. I just think Nintendo is gun shy about Eternal Darkness. Didn't Dennis Dyack approach Nintendo at the start of the Wii U generation to either make a sequel to Eternal Darkness or make Shadow of the Eternals Wii U exclusive? And despite being a massive Silicon Knights fan Shadow of the Eternals is basically vaporware... Eternal Darkness never sold well on the Gamecube and with how Silicon Knights went full 3rd party I think really soured that relationship.
