I found Dark Souls II to be disappointing due to both the easiness of its non-optional areas (the optional ones are fittingly hard as hell) and the lack of isolation due to the well-populated hub area. That said, it's still a great game, though in my opinion, not as wondrous as the original.
The PC port has issues but is overall a better job than DS1's. If they haven't yet fixed it, you will need a hotkey program to bypass the mouse click lag so you can attack competently.
The early access weapons available in the Black Armor edition are normal items in the mid-to-late game - however, copies are added to your inventory immediately after character creation in the Black Armor edition. The comic is somewhat negligible, but the art book is nice.
