This is the first Final Fantasy game of all time. Where to begin…
Okay, first; do not buy unless you are prepared for an OLD game (1987). The graphics are dated, but are as good as it gets for games this old. The level system is a cliche, the story is a cliche, the characters are a cliche. However, this is probably your best shot at getting a classic game like this one.
Also, the 1st half of the game is average. The second half (once you have the airship) is awesome, 5 stars if you don't overplay it.
As far as PSP games go, this one's good. Give it a go.
