I don't have a particularly strong interest in ever playing Nioh but it's nice to hear this game is doing well in the West. For a long time it seemed like Tecmo was a Japanese company that designed games specifically with western audiences in mind but recently it has seemed like they had lost that audience almost entirely (or it at least wasn't as big an audience as it was).
We know a lot of our fans in the world have been waiting for the next Ninja Gaiden and it is one of the most important projects for us as well, he says. At the moment, we are not in a position to announce anything, but we are hoping to share good news with you once we are ready.
Team Ninja needed Nioh. People had lost faith in Team Ninja's ability to make great games that didn't have DOA in their name. As for Ninja Gaiden my guess is that a new Ninja Gaiden will go into preproduction soon. Just a guess. They should take as much time as they need as they need to get this game right.
I have the unpopular opinion that NG2 (I'm including Sigma 2 with this) is the best game in the reboot series and NG3RE is number 2. I've owned every version of the reboot NG1 and have beaten it but only because it always felt like a game that SHOULD like so I kind of forced myself through it. For whatever reason it never grabbed me (I think my issues mostly stem from the progression system and the pacing of the game). It's funny because I actually really like NG3RE but I consider NG3 vanilla to be utter trash.
Whatever they do with NG next I don't think it can really be a direct sequel to what they have been doing. Even though Itagaki wasn't involved with NG3 I feel like the entire reboot trilogy very much reflects Itagaki's style. I think they should make a clean break and do something completely new with the series. Having said that, I think remaking the NES trilogy in the reboot NG2 style would be awesome.
