After Final fantasy XIV 1.0 was a gigantic flop, Square Enix was brave enough to give the title a reboot.
A Realm Reborn is really fun. This already starts with the story which is very long in my opinion. The atmosphere and the music are wonderful. Every detail in the game is lovely designed. There are so many possibilities in the game to kill time. For example, there are FATEs which are events where you must fight in groups against world bosses and other opponents. Even if you've reached max level, you can still enter old dungeons because your level gets capped and you can enjoy them with newer players. If you're bored with your current class, then you don't have to create a new character. Just change your weapon, and you can play as another class. I really like that idea since I don't like to have multiple characters.
If you're a Final Fantasy or MMORPG fan, then you should definitely give this title a try. It's one of the greatest MMORPG's in recent years. I've never had so much fun with an MMO like with this one.
