-Ending Theme

-And then Asate kanae tsutamae (faith song)

-The battle song is also good 

Between Final Fantasy and Metal Gear Solid

i choose Final Fantasy and Metal Gear Solid

You don't play as "Solid Snake" you play as Big Boss (Naked Snake)

and there are a lot of improvements that will cost you a lot to adapt

English i More fun games and in most cases just searching to get big sells (and in some cases bad graphics,story,gameplay)

Japan are more intelligent games with more deeper stories and in many ways better games (They put more effort on games)

2 has more metal songs(hangar 18, sweet child of mine,mother,war pigs)

and 1 is more soft (Ziggy stardust,stellar, i love rock'n  roll)
