Hmmm yeah, doesnt seem to be much actual discussion about Breath of Fire: Dragon Quarter. Although i missed out on BoF 3 and 4 on the PS1 i would count myself as generally liking the series after having played BoF 1 and 2 and enjoyed them both thoroughly.
I had been waiting for Dragon Quarter to be released, not truly understanding how the battle system worked and such from just previews, and i still didnt understand it after playing it a bit. But you soon get the hang of it, and i found it to be a great system to work with.
Someone earlier mentioned the drab scenery and such and while i do slightly agree, it has to be taken into account that the whole game takes place underground (in aid of the story) and while the scenery is nothing special, i think the character design oozes appeal, being a fan of good cel shading.
I've recently completed it for the first time, and hope to return and complete it again after a break to unlock more cutscenes, areas and goodies etc. Despite the story not rivalling some of the greats, and a linear progression throughout i found the game a joy to play and now stands as one of the best RPGs ive played.
Anyway, i recommend it, but you might want to rent it or whatever first to make sure that this type of game doesnt bore you, as it has some people.
