In the current game, the most popular content are Frontlines, Syrcus Tower (Crystal Tower 2), and Second Coil of Bahamut. Hunts were violently popular until 2.35, now not so much. Also, you're gonna want to get your hands on the newest relic weapon upgrade soon, because supposedly the next Zodiac Weapon chapter's getting released in 2.38, which will effectively make it the most powerful weapon you can possibly get in the game.
