Well i have the title, and to be honest dude just do what seems right to you. When i did the quests i chose all the options that seemed to me what a rugged bounty hunter would do, like killing everyone, not sparing a life, pissing off mako, the usual. I honestly wish i could remember every detail that i did so i could be of any more help, but if you ask me, i wouldnt play this game for a title anyways, once you unlock your legacy, that should be enough if you ask me.
