"You know, it's not very likely that a game is remade just a few years after its release. But it's also not very likely for a remade game to receive an overhaul instead of just an upgrade. That is precisely what Ninja Gaiden Sigma is bringing to the table; a complete overhaul that shares few similarities with the original. As we anticipate this overhaul, Tecmo has thrown a bunch of new details our way. In fact, so many details that we had to dedicate an entirely new and updated preview for the game."
