Phantasy Star was by far the best console RPG of the 1980s, not counting PSII released in 1989 in Japan but not until 1990 in the west.
Phantasy Star pisses all over Final Fantasy I, II, III, Dragon Quest I, II, II, IV and any other console RPG of the 80s, including all other Master System RPGs.
nothing, and I mean NOTHING can prepare you for the final battle in Phantasy Star, against the greatest evil in the entire universe.
