Uh.. Xenogears was published and developed by Square. Breath of Fire on PSX were published and developed by Capcom, and as far as I know the SNES Breath of Fire's were published and developed by Capcom
Ahh you're right, Xenogears WAS developed by Squaresoft. I forgot the team that developed Xenogears went over to Namco to develop Xenosaga. However, I know Breath of Fire for the SNES was not published by Capcom - it was their first RPG, so they wanted the RPG giant Squaresoft to publish it for them. All Breath of Fires afterwards were published by Capcom, of course.
