Thank you, thank you, thank you for compiling this guide. I just started this game (yes, a tad late to the party.) I tried my very best to avoid the spoilers (seemed I did an okay job of it, as you helped quite a bit with that with your organization) as I perused your Guide - and I can tell this is going to be massively helpful with achievements.
I love collectable achievements like this (I don't know why. Can't really explain it.) - and I know how much work goes into the Guides - so I very much appreciate when I come across one as detailed as this. Again, thank you. You're awesome.
