It's a pretty good game with a memorable (playable!) antagonist, a pretty advanced battlesystem (swap teammembers mid-battle, use combine attacks to create new moves and increase your damage output!) and neat little sprites. If you're new to Breath of Fire, you might as well start with this one. Or maybe Breath of Fire III, that one is good too. The earlier games feel very dated and Breath of Fire: Dragon Quarter, while a really awesome game, scares off a lot of people with its unique and challenging gameplay.
What am I saying? Everyone should play Dragon Quarter! It's a gritty reboot that actually worked, it dares to be different and does it well, and it's perfect for anyone on a diet of MegaTen, Demon's Souls and Nier (which is like, 95% of the people who post on these forums?)!
Oh, but this thread is about the fourth game isn't? Yeah, that one is good too, in a more traditional kind of way.
