I've finished just about everything in my first run through, although I missed a handful of things.
Accidentally killed the harpie blacksmith and overlooked the other guy
I was thinking of just jumping into NG+. I started another character but I can't see myself playing anything else then what I have already, and what I also used in Dark Souls.
I'm basically Vig, End, Vit and ADP. Magic/Miracles/Hexes/Pyro are boring but stat scaling is also crap so...
I was also going to try the champion covenant and going fisticuffs eventually but I don't like the idea of having to play perfectly on bosses/mobs, slowly chipping away at their health.
The only things that's really kept me playing has been the invasions, which are more dynamic than the stuff you find in the arena.
Earlier today I carried a torch around for a guy as a red phantom for a bit. For whatever reason we ended up naked except for helmets and ended up slowly beating each other up with fists before he finally did the "begging for forgiveness" gesture when I got him down to a sliver of health. I waved goodbye and black crystalled out.
I also had two sunbros and a host chasing me in circles around the Dragon Shrine for about 15 minutes when I got duel summon ganked.
