MUCH faster, no stamina bar, and waaaaaaaaaaaaaaaaaay more "things to do". There are a ton of systems and stats in it, but once you get the grasp of things it's not too bad. There is also an actual storyline (though told very badly), and people always call it the "samurai Dark Souls" when really it's a mix of Dark Souls and Diablo 2. The way loot works is why that game is so fun. You can go as far as you want.
The issue is Team Ninja made it, and those people are just indefensibly stupid. The camera problem is the worst in Nioh, too. It's bad with From Software, but TNinja didn't even try. I wrote a review about it.
