7. Eternal Darkness: Sanity's Requiem
Eternal Darkness: Sanity's Requiem is one game that just needs to be re-released, period. But, given that it's a Gamecube title from 2002, the graphics frankly don't stand the test of time. The horror of a good scary game is supposed to lie in a perfect blend of atmospheric intensity and psychological agitation crafted by the writers, not the crudeness of bulky polygons from a bygone era. With a high definition remake of this unique psychological survival horror hit, Nintendo would also have a chance to hit the refresh button on one of the few mature games to grace their consoles in the past few decades (in fact, the first M rated title to be published by them and not a third party developer), helping to repair their image as being unfriendly to adult audience titles.
Sadly, a Wii U sequel was scrapped due to legal issues with developers Silicon Knights, making a re-release of the original unlikely.
