Very interesting Topic !
I will have to listen a little more at the CD of the original soundtrack ! Because I can't make a list so important without a good listening and make choices.
But I can tell my vision o the best to "worst" soundtrack of the 4 PS from the "first generation game (I'll not speak about the other ones, even if I have played a lot (many hours !! Too many...^^) of PSO and a little bit of PSU.
1.Phantasy Star 3
2.Phantasy Star 1
3.Phantasy Star 4
4.Phantasy Star 2
@ KALOES : Speaking about those CD's from the 20th anniversary/Birthday, I checked the music of the title theme and the title is no more than...title !
A bit disappointing...maybe a more developped title would have been more enthusiastic but...maybe from other sources can we find another name for this one ? Or maybe title is the only and definitive name.
And Finally I, too, agree with aug4th on PSII's music : not really bad but not really good...but some very good ones ! (cf my ranking).
PS : a bit "surprised" by the ranking of PS3 in certain lists ! But everybody got different likings so...
