What a disappointment. Legend of Heroes is one of my favorite series; I played Sora no Kiseki in 2007 or so and have played all the games since then except Sen no Kiseki III (I don't have a PS4). I certainly didn't expect the earliest entries to be masterpieces, but I hoped they'd at least be playable.
Legend of Heroes was originally part of the larger Dragon Slayer saga, a series of PC games by Falcom. Like most of Falcom's games, it was originally developed by them for PCs and then ported to all kinds of different consoles by other companies. The PC Engine version was developed by Hudson. Zenic covered the first game, which did come out in English. It doesn't sound like he had any particular problems with it.
Then we begin the game.
