Phantasy Star 2 and 4 are epic. 3 is good too, but not as epic. Like ed said, it's interesting none the less. And I believe Phantasy Star 2 is one of the games everyone has to play at least once in their life. The dungeons are hard and pretty unforgiving. The story is very interesting too. Especially when the enemies change from biological to mechanical halfway through and one of the best characters starts to suck and one of the more sucky characters becomes awesome.
