Honest critiques about 10-15 hours in:
-Certain areas in the game are damn dark. I've got brightness cranked up both in-game and on my TV, with my torch out, and I can't see shit in some places. It seems like most of the later areas I've been to don't have this problem. I understand mood/atmosphere (like Tomb of the Giants in DS) but it's a bit much for me.
This is one of the best things about it. You need to use a torch or the belt mounted light. (Or both.) I have my TV set so that when it is dark it is extremely dark and it feels like how it is meant to be played.
Dark Souls 2 is much much better if you set your TV as dark as possible, but the torch mechanics in Bloodborne outclass Dark 2 in all ways.
