Short answer: Yes
Not so short answer: I've tried many MMOs for what I think are a little more than ten years now, but none of them could grab my attention for more than one or two weeks not even playing with friends and family. Guild Wars 2 came pretty close, but since I only now in real life one person that has the game but stopped playing I play mostly by myself. FFXIV I think it's excellent to play alone or with people, but unlike most I've tried, this one makes is extremely easy to group, thanks to the Duty Finder.
Some people may complain about people who "don't know how to play" but honesty, the games gradually shows you the ropes on how to play. I personally never had a problem with a party.
So in the end, I recommend it, especially if you are a Final Fantasy fan.
