Great Rumbler Recommends: Phantasy Star II

[A Black Falcon]

Hard and impossible, with dungeon mazes that absolutely require maps (from the internet, preferably).

Really, it's only worth the effort if you love old-style "you will only play this game if you hate yourself" kind of RPGs... like Roguelikes, or '70s/'80s dungeon crawlers like PS 1 & II. :)

(And yes, I have PSII for Genesis.)

Oh yeah, and in classic PS tradition (PSIV is just as bad on this), the plot is really depressing.
