Where The Witcher 3 and MGS5 may fall down comes from a feeling of repetition that can begin to accumulate over time for the player, with an immense open in world in The Wild Hunt and Limited areas in MGS5. I have read the Wild Hunts swordplay does not hold up over the extended journey while MGS5 has received an admittedly mixed reception from players due to an apparently underwhelming story but also that with limited areas some of the offline content is just more difficult versions of earlier missions. It does seem though that The Witcher 3 has provided more overall satisfaction with the final product.
