I'm like pyrenus. Never played the beta, hadn't read much on FF XIV before deciding to buy it and play it, and am absolutely clue-free in my wanderings.
After getting everything registered, paid for, signed, sealed, and stamped w/the Square Enix seal of approval I got in the game, walked around absolutely stunned by how pretty everything was, and then struggled mightily with the UI for some time. After finally figuring some basics out I think I got to either 3 or 4th physical level and around the same as a blacksmith.
Had lots of fun too, despite the wrestling with the UI bit of it. Did I mention how beautiful the game is yet? =:-o
