Phantasy Star Online Episode 3
Most people today don't recall this game. It was a Gamecube only game. However, it was a rather unique title for its time. The game is a collectable card game, one of the first few games of its sort to be online, joining the likes of Square's Tetra Master and Wizards of the Coat's Magic Online. Some may compare it to BandaiNamco's own entry that existed a few years ago, as it's also a strategy game. I do recommend getting it if you can find it.
