Hey, I don’t think anybody heard of these online games before, but they’re a couple nice mmorpg games for Final Fantasy created by fans. They’re retro style like the NES and SNES so don’t expect anything but nostalgia 
Before you can play them you have to download the Byond client: download
It’s basically a network game client for all the games created with Byond. It helps when creating Byond games when you have no networking experience…
Anyway, after you installed the client, create a Byond key on the site (it’s like registering to become a member, but free). Now you can log in to either of these two games by clicking on the “Join” link under the “live games” section (or any other byond game):
Final Fantasy Hunting Grounds (FF1 NES oriented)

Final Fantasy Legacy (FF4 SNES oriented)

Final Fantasy Online (byond version)
A more “adventure” typed Final Fantasy game with the MMORPG concept, which tries to imitate Final Fantasy 1, 2, and 3 to an extent.

Enjoy!
PS: Any questions just ask in this forum and I will try and help you log into the game.
