I thought that it was overall good fun. The battle system is excellent and the music is great. The characters are cool and generally quite enjoyable. However, the standard ending of the game really annoyed me. It’s totally anti-climactic. I really don’t want to go back and do a bunch of side quests (collectathon in particular) to unlock the true ending.
Anyone who says Sea of Stars is in the same echelon as "classic" JRPGs clearly didn't play all the way through SoS or has not played many classic JRPGs. SoS was an okay game for what it was but I honestly don't remember much about it a couple of months after finishing it, whereas games like Lunar and Persona will always be cherished gaming memories for me.
