Yeah, but now were back to sheer numbers, the RPG side of the game and the possibility of stacking up ability to tank shit either via Blocking or just taking it on the chin. You get enough HP, armor, damage reduction etc and you will survive it. I play a very quick and fragile build myself, but the game does allow some rather spectacular tanking if you pile it up.
I kinda always forget that you can do a tank build in this game lol. Yeah you can survive anything if you want to and nothing is guaranteed to kill you, no matter what you wear and stats are.
I'm not defensive, just think that the similarities are like say, Virtua Cop to Panzer Dragoon.
Combat systems are as different as any two action games, level structure, encounter design etc.
Outside of Amrita=Souls, except since it isn't used to buy stuff, that's it really.
Nioh is NGB + Diablo. Both of those games existed before Souls.
I would say it also has Souls DNA a bunch too.
edit.
To be fair you can't even guarantee that a Souls fan will like DS2 or Bloodborne.
