Great game. It meets the high expectations set by the previous Dark Souls games. That, of course, means it's super hard.
Dark Souls 3 combat adds a new element from prior games. There is a set of "weapon skills" that are best utilized by non-magical characters. They can be extra strong weapon attacks or a buff to your stats. I like them. Like everything else in Dark Souls, they're hard to master but very rewarding.
Enjoy, and prepare to die.
