It's hard to put a finger on exactly what's so bothersome about Phantasy Star 0. On one hand Co-Optimus really liked the direction the single player is going, on the other, the online component is starting to feel a bit aged. Phantasy Star Online came out almost 10 years ago, and the formula hasn't evolved all that much since then. The game is clearly designed for fans of the series and people who love loot collection style action RPGs. If either of those are you - you'll probably want to give Phantasy Star 0 a go.
