The first Trails in the Sky was very draining for Xseed financially, which is why there was such a long wait between its release and Second Chapter. The Legend of Heroes games are very heavy in dialogue. And First Chapter is smaller than Second or Third Chapters. They contracted the second game's translation out to a company called Carpe Fulgur, and the guy who leads that company supposedly had a nervous breakdown while working on Second Chapter due to the pressure. I don't know if Xseed handled the translation of Trails of Cold Steel or if they contracted out to Carpe Fulgur or some other outside party.
