If you own a PS4 (if you don't, you're missing out!), you can try out Final Fantasy XIV: A Realm Reborn as part of the game's open beta test from now until April 7th.
The test, which started this morning and runs until April 7, will allow anyone who owns a PS4 to jump into the MMO without needing to register beforehand. Additionally, the test makes use of the live servers, meaning you'll be playing alongside both PS3 and PC players and, if you decide to buy the game when it releases, the character you make this weekend will be carried over for you to use.
