I've got the same thing, but I am getting this. It's up to you, but it is a straight-up remake as opposed to a port or something. I understand that the subtitle, 'Wii Edition', is a bit misleading, but it's essentially the equivilient to Resident Evil 1 REmake on Gamecube if you ever played that. It was remade from the ground up, and does include new story chapters, new locations, new enemies, new scares, new endings, redone graphics, redone cinematics and voice acting, new modes, redone music, and new mechanics. It was built using the Fatal Frame IV engine, and as such they seem to have adjusted some of the scares to work better with that game's mechanics and camera style.
