Hm, I wouldn't say it's overrated. It had a great story, well developed characters and an awesome soundtrack. I guess that's pretty much what I ask from an RPG. It's too bad they never realesed it here in Europe though.
What the cat said, great story, well developed characters, awesome soundtrack, what more could you ask for. This makes the RPG at least good. After that, it seems to come down to which games had the characters and music and humor I liked more. Story I don't seem to focus on as much unless it really blows me out of the water (which is pretty much the only reason Chrono Trigger's high on my list. Other than that, it just doesn't seem as accessible as some of the other RPGs I've played).
You may complain of monotonous battles. Well, I'm a turn-based RPG diehard, it's the style I prefer and don't get tired of, so the battle system's no problem. I eventually got used to the battle system in Chrono Trigger (after I realized that with the "Wait" mode, the time to attack again is a cool way of indicating move order), but I still prefer to have time to think out my moves. Granted that most of the time it's just slamming the attack button, but I'm very sensitive to being attacked twice by an enemy before I can move. Plus, the 30-level cap might help to lessen the level-grinding issue. I don't recall spending much time upgrading my characters before a battle. But in EarthBound, there was level-grinding a plenty.
And it's pretty fun to finally play as Bowser.
By the way, I voted for not overrated. It was just great all around. I didn't think it was a religious experience when playing it, but it was unique and remains one of my favorite SNES games (among a ton of others).
