You can play The Legend of Heroes: Trails in the Flash at home on a PlayStation 3 connected to a big TV and take your game on the go with the Vita version. In an interview with Dengeki PlayStation, Falcom confirmed players will be able to transfer save data. There are no differences between the two versions when it comes to content.
The Legend of Heroes: Trails in Flash is said by Falcom to have the largest story in the series. When making a plot outline the amount of story in the game is equivalent to four light novels. The story takes place Erebonian Empire before other games in the series. Falcom is keeping the specific time period as a secret for now. Remember the great invasion of the Erebonian Empire referenced in The Legend of Heroes: Trails in the Sky? Players will see that war unfold in The Legend of Heroes: Trails in the Flash. So far, four protagonists have been shown and Falcom says they have more heroes to reveal. The character designer made about 60 to 70 characters. Falcom is still looking for voice actors for them.
Familiar characters and organizations will be in the game as a treat for fans, but The Legend of Heroes: Trails in the Flash will introduce these as if they were brand new to make it easier for new players to understand what’s going on. The raiding force is not the Crossbell Police, but a new organization.
The Tactics Link System has been changed because players went through phases of watching and waiting. This game will be more active and players will always have to think about what actions they want to do while moving around. Orbments have cooperative actions where you can link up with another character.
Characters will chat more with each other in Trails in the Flash. There are Active Voice Events during battles and while your on the map. Bond events have also been enhanced.
It sounds like Falcom is planning to expand the game with downloadable content. They told Dengeki PlayStation there might be costume and/or scenario DLC.
