Which would you rather support? I've completed both factions and they are equally satisfying and equally beneficial to society in their own way.
Whenever I get to the point in the game where I have to decide between the two, I spend days pondering the better choice. And in the end, I always end up questioning my decision and I ponder about whether I made the right decision or not.
On one hand I become the Director and shape the future of the Institute and their goals, allowing me to hand pick the institutes agenda and create the world into something I deem fitting, though once I die it runs the risk of reverting everything I created. While on the other side I rid the world of what could actually be the worst threat to mankind, I join a faction that has actively fought against mutants rather than create them (Institute), and I become the sentinel of the Brotherhood basically giving me the ability to influence what happens afterwards and become the adviser to Maxson or the Merlin to Arthur if you will.
So, out of these two faction which would you support and why?
