Last month brought news that Ryu Hayabusa was making a comeback on Switch with Ninja Gaiden: Master Collection. Featuring the three rebooted entries - Ninja Gaiden Sigma, Ninja Gaiden Sigma 2 and Ninja Gaiden 3: Razor’s Edge - some fans aren't happy this trilogy collection uses the "Sigma" editions.

In short, both Sigma games were altered PlayStation 3 re-releases - ones director Tomonobu Itagaki didn't have brilliant things to say about - and featured notable gameplay changes from Ninja Gaiden Black and Ninja Gaiden II.

Now, we've got an explanation as to why Koei Tecmo made this decision, and it's not good news. Speaking in the latest Weekly Famitsu, Team Ninja brand manager Fumihiko Yasuda explained:

I am aware there are pros and cons. For me personally, Ninja Gaiden II was my debut, and so I have a deep feeling for it. But there’s another reason for this choice. To be honest, there are only fragments of the data that remain. We couldn’t salvage them. However, when developing Sigma Plus and Sigma Plus 2, we got as much of this kind of data together as we could and organized it. Because we use utilize that is the reason why we selected Sigma.

It highlights the pressing issues surrounding games preservation, a subject which separately flared up this week after reports emerged that Sony might shut down their PS3, PS Vita and PSP stores by Summer.

Even if it's not Ninja Gaiden Black, we're still pleased Ninja Gaiden's back.
