oh, didn't know you wanted to make it yourself heh. Well I'm afraid I cant help ya then, as my job is to write music for games/film. If you want to make Final Fantasy type music(and still have its quality) its gonna take 3 things:
1. Lots of money:
Nobuo Uematsu, the composer for the Final Fantasy games, is a professional who has an entire studio dedicated to his music production. From Keyboard and Rack-mount Synthesizers to software samplers to mixing consoles. A BASIC and decent(with the emphasis on basic) home studio setup will cost you well over 5 grand.
I can't find a decent picture of Nobuo's studio, but I can assure you it looks something like this(Hans Zimmer's studio)

2. Lots of knowlege in music theory and music production
You can't expect to use pre-made loops and get Final Fantasy type results. You will have to write out your compositions note by note and know exactly what you are doing when mixing and mastering to acheive the best and most original results.
3. Patience
Music is not an easy hobby to have. It takes a LOT of time, practice, and effort to get good at it. Its like programming, you cant expect to just buy a copy of DBP or some other engine with little or no experience and make the next big game. The same goes for music, you cant expect to make music with the quality of Final Fantasy when you are just starting out.
I'm not trying to push your hopes down or anything, Im just warning you of what you are in for if you are hoping to make Final Fantasy quality music right off the bat.
