No random encounters, only two people in your party, the option to have the computer control your partner... this is no doubt the easiest Final Fantasy. But I think one of it's few (if only) high points is the soundtrack. What do you think. If you want, here are some samples:
Aqua City
Battle Theme
Boss Theme
Focus Tower
Fireburg
Doom Castle
Opening Hill
Final Confrontation (Final Boss)
Forest
Mine
Pazu's Tower (also used in Mtn. Gale)
Tristam
Volcano
