Phantasy Star Online Home Page
Phantasy Star Online - Episodes I & II was one of the most addictive MMORPG's on the face of the planet. While the multiplayer modes have fizzled out and died off over the years, primarily due to item duplication hacks and other game exploits that could not be prevented, this game is pretty much dead.
The single player mode does offer a slight bit of entertainment value, but if it's all you've tried you're completely missing out. There is a quick and easy strategy for leveling up a character for solo play though.
