Bad Export for You: The Xbox LIVE Arcade version, as it lacks the Story Mode and Arrange Mode from the Sega Dreamcast port. And to put salt on the wound, Trigger Heart Exelica -Enhanced- for the PlayStation 2 was released after the XBLA version, which has most the Dreamcast's version feature plus a fully-voiced Story Mode and the ability to play as the original Faintear.
No Export for You: The aforementioned Trigger Heart Exelica -Enhanced- re-release for PlayStation 2, which also includes a Limited Edition with a nendoroid Exelica figurine from Good Smile Company fetching around $150-200 at auction and importing stores.
The Merch: The game has spawned a guide book with strategies, artwork, and concept art of the game, and an Audio Drama CD by Frontier Works that was divided into two parts: one for the story and one non-canon section made for humor. There was a 1/8 scale PVC figurine of Exelica released in 2008 by Alter and another by Toy Works in the same year. A set of Exelica, Crueltear, and Faintear figurines was also released in 2010.
What Could Have Been: According to the game's guidebook, Crueltear was originally supposed to be a mecha, rather than a Triggerheart like Exelica.
