Thanks to IGN Cube for their article taking an in-depth look at the U.S. version of Phantasy Star Online Episode III: C.A.R.D. Revolution
for GameCube. They note the advantages and disadvantages of the GC-exclusive online CCG title: "Since it is a PSO game, the legions of fans that can't get enough of dungeon crawling will immediately be interested in PSOIII, but since it no longer holds the same basic hack n' slash mechanics that made Episode I so popular, Episode III by its nature will turn off many of the same fans that are meant to embrace it."
Over at PSO World
there are multiple resources for the import version of PSO: Episode III, including a card database
and a guides section
, and the site also has news on an in-development PC version
of Phantasy Star Online: Episode 1 & 2, though a U.S. release for that is as yet unknown.
