How to enable Hardcore mode

Why Hardcore mode is disabled and grayed out in gameplay menu settings? I am an "expert" of Fallout 3 and I would like to start my first playthrough in New Vegas with Hardcore mode ON. Is there any workaround?


Solution 1:

I believe that Hardcore mode is only available after you first start the game and finish a few quests in the starting town. I too looked for this option and had it greyed out, but when i tried to leave the starting area it asked me if i wanted to play HC or not, explaining what the difference is.
