Chrono Trigger: Crimson Echoes was a fan-made ROM modification for the widely-acclaimed SNES RPG Chrono Trigger. I say “was” because Square Enix have sent the fans a Cease-and-Desist letter, letting them know that if the project is released, there will be a lawsuit. The mod “featured ~35 hours of game play, 10 multiple endings, and 23 chapters, much like the original Chrono Trigger; it was around 98% complete.” As ZeaLitY says, the game was made only out of the goodness of fan’s hearts and certainly not for profit. The video above is the trailer for the game, made this year.
I must say that I feel this is a bad show on the part of Square Enix. This was a fan-made mod, with no intent for profit, and people had spent countless hours of their lives in the process of making this game. What harm can a mod like this do? Surely it can only provide free advertisement for their game. My consolations to the fans who put all this work into the game only to have it completely trashed.
