I really wonder what would have happened had Fujiwara stayed at Capcom instead of forming Whoopee Camp. Would his versions of 3, 4, and 5 have been drastically different from Ikehara's? Especially since Ikehara seemed like he tried to make the games in the way he thought Fujiwara would have.

(for those who don't know, Tokuro Fujiwara directed the first two BoFs while Makoto Ikehara, previously a planner, directed the last 3 games)

Since I always seem to do this type of thing, here are all the BoF games so far, some of them with notes:

Breath of Fire (SNES)
Breath of Fire 2 (SNES)
Breath of Fire 3 (PSX)
Breath of Fire 4 (PSX)
Breath of Fire 4 (PC) - the font is different compared to the PSX version, and there were minor changes to the dialogue in the European versions. Graphics are also a bit clearer too.

Breath of Fire (GBA) - streamlines the interface, and multiplies zenny gained by 4 compared to the first game. Much easier to get equipment now.

Breath of Fire 2 (GBA) - streamlines the interface, double experience and money compared to the original 2.

Breath of Fire 3 (PSP) - Adds fishing mode and a couple other modes to the main menu (the fishing mode has ad-hoc multiplayer), Pilfer seems to have a lower chance of working, especially in the beginning of the game, Beyd sounds different when you train him, Stallion's color scheme was changed so that he doesn't look much like Ultraman anymore and Utmost Attack is called Vortex Wave, and there's all sorts of other little differences.

Breath of Fire: Dragon Quarter (PS2)

There's also all the mobile phone games, and they were all based on IV. A card game, two RPGs, and an enhanced fishing minigame.
