I got into it a few years back and nearly finished ARR. I found the storyline and cut scenes really engaging, and felt like I was a part of something. But I tried to pick it up and start fresh about a year ago and the bastards oversimplified my class (Summoner), and I swear they even further nerfed the low-mid level difficulty, making me feel most days as though I was playing on creative mode. For those who don't care, though, the storyline, world and music (holy fuck, Limsa at night and Ul'dah at night are absolutely soul stirring) are really something special.
I will likely try the game again with the upcoming graphical upgrade, but I fear I will always feel too behind on the story and won't be a part of the entirely new storyline/age that is slated to begin with the next expansion. That graphical upgrade will be huge, though. I play a ton of old games myself, but sometimes FFXIV feels like it's running modern character models over PS2 environments and grass textures. It deserves to cast off some of that jank and show how beautiful it's natural world can be.
