Land of opportunities is the stupidest thing. I did the story missions in free roam plus you can re play any story mission you want when you want. Go into menu and select progress and click on story and replay any story mission you want. I bet Rockstar will pull that out after they add more content because it's really redundant unless you're a newbie, but then again the story missions show up in free roam unless they removed them? Or people don't realize they can replay them from the menu in free roam?
