Is Final Fantasy a good game?

They're usually fun and very engaging. But it depends on what you like to play.

If you like fast strategy games then I wouldn't recommend it. They're something like

-----------------

l > Attack l

l Magic l

l Item l

l Flee l

l-----------------l

Then it will hit the enemy then it will subtract it from the enemies' hp until it dies. It's kind of a slow based stratagy thing.
