Secret World is a dying mmo with a cool (albeit unfinished) story and cooler puzzles. It is set in an urban fantasy world where magic is real and most every conspiracy theory is true in some fashion. Working for one of the big three - the Templars, the Illuminati, and the Dragon - the player character is tasked with investigating and containing occult disasters across the world. Wish it wasn't dying but good thing is you don't need to play it as an mmo to experience the story content. Hope you know morse code.
Dragon is obviously best faction
The Templars were probably full of deus vault losers back in its prime and the Illuminati are just straight up evil if the canon is based on even remotely decent research
If there's one thing the overall story slowly makes clear is that your bosses are not good people. They are at the head of ancient immortal organizations that seek world domination, with more than their share of skeletons in the closet. The Illuminati are the most obviously evil and the first person you meet literally says 'the United States became a superpower off of the Illuminati becoming the supervillain'. So you're not far off.
I ended up picking them because they are the funniest.
