The game does really get quite punishing if you stay good... so far, I've only had a few moments of frustration, not quite enough yet to tip me over to being a monster... but there was this one moment when I was considering it!
I'm really hoping Bloodlines 2 will be great... I'm pretty hyped for it (yes yes, the set up for dissapointment...), what they were able to do with the original with the limitations of the time was just mind-blowing, and the setting was nothing that I had ever experienced! Still, I hope they don't dumb it down for the console guys!
I finished the game with minimal bloodthirst, so not at all a monster, but not a saint either.
I expect Bloodlines 2 to be more of a modern game along the lines of The Outer Worlds. They have promised it'll be a deep experience, but of course, the best intentions don't always lead to the best product.
