Well... I finished it...
*Possible spoiler* My path...
Created every settlement with excess bedding, complete fencing, excess food/water, multiple full rotating guns, two lasers and two rocket launchers. Once I did this the amount of times they got attacked was nearly zero. I did most of this game in wondering mode. Depending on my mood. Sometimes I ran just jobs. But during the jobs I would explore. Other times I just explored.
My goal was to see if I could complete the game with everyone at peace. I was not able to find a path to do that. Kind of sucked. I tried multiple conversation tactics and job selections.
Then ran all the work that the Railroad asked me to do. Only stopped when I had to decide who I wanted to make my enemy.
Then I did all the Institute stuff, till the same decision point.
Then I joined the Brotherhood, killed the railroad and institute. Now I am just wondering, need to start a new character...
Total time 8 days 15 hours (Keep in mind, each time you go back to a save and try a different tact, the timer does go backwards with you, the time is the path/game time, not total gaming time).
