i honestly want to know what old world blues is about and how good is it and what skills are needed to effectively utilize the DLC?
Old World Blues...is a saying used to refer to those who are obsessed with the past. The Big Empty is a fully functioning pre-war research facility, complete with experiments. Some horrific, some benevolent, all crazy. Old World Blues is a masterpiece of humorous dialog and backstory- it's pretty much a crime to click through the dialog and not read the notes. The gameplay itself is very well done, in my opinion. Plenty for the shoot em' up players to recklessly attack, plenty of strategizing for the rest of us.
As for the main storyline...the only thing I will say, since I won't give away spoilers, is: Curiosity killed the cat.
To effectively utilize Old World Blues, you should have high Science & Medicine, with points in Energy Weapons. Although anyone can benefit from visiting the Big Empty.
