It's my second favourite FF game, only behind Final Fantasy 9.
I overall didn't enjoy the story in A Realm Reborn much (outside of the 'Binding Coil of Bahamut' raid storyline, which i recommend you do at some point if you haven't already), but Heavensward's was great, and Stormblood has been fan-fucking-tastic so far. My desire to strangle Yotsuyu intensifies with every step i take.
It's the gameplay that's kept me playing though. Every class has so much depth to it, and there's an ungodly amount to learn and explore. Since 3.0 they've also started experimenting with entirely new types of content, which has been great. My favourite so far have been the deep dungeon (I've so far made it to floor 180), and the Aquapolis (which is a glorious loot clown fiesta).
