followed by a solid cast (except for Tio)
Tio was a great character when combined with the whole Mareg 'thing'.
(That and dear lord Lotus Flower was OP)
The battle system of G3 was enjoyable, but the difficulty level was really uneaven. Sometimes it was too easy, the next moment, it was tough as nails, and then back again. It almost made me seasick.
This is the big reason I never got it (though I'd like to get a cheap copy before the opportunity vanishes), I didn't care if the story was bad so long as the gameplay was great, and apparently it was... except with an erratic difficulty level undermining it. I'd rather have stupidly easy (Grandia II) than that.
I got mine for 15 bucks, and it was worth the money.
As I recall, there's 2 bosses and 1 random encounter that made me really cringe. The rest was OK.
The worst one was a boss that keeps spawning minions. If you aren't strong enough, you just fall back behind and end up not ever having time to attack the boss... and then it just goes down to sucking.
