With Hollow Knight: Silksong’s huge launch in full swing, community debate about its qualities and flaws has gone back and forth, with some players insisting their criticisms about things like the game's difficulty are valid and shouldn’t be instantly dismissed as "hate."
I was mostly thinking of NG2, yes. I enjoyed NGB, but NG2 is the only one I replay, and it’s mostly what I’m thinking of when I bring up Ninja Gaiden.
We can even go back further and bring up Bayonetta (2007), God Hand (2006), or even DMC 3 (2005) All are tough as nails, but super fun.
