The excuse I have heard time after time is the character design's are "too childish". People should have their own opinions and I would respect those opinions but I still think the "too childish" is a poor excuse to not like this game. Obviously after FFVII and FFVIII it took a U-turn and went back to old style FF games as FFVII and FFVIII which helped bring the series into mainstream was more futuristic.

Anyway, I thought this game was excellent that I even like it better than FFVII (My first FF and was my favourite). I love the characters. The relationship between them (Zidane & Garnet, Zidane & Vivi especially). The story was great with a lot of well timed humour added into cutscenes and some very impressive FMV's, especially for its time.

I still think this game doesn't recieve a lot of credit and I also agree with gothic_fantasy that FFIII also doesn't recieve as much credit but that is probably because it never seen a release outside Japan until last year.
