As I previously posted, I've decided to catalog a list of differences that I noticed between the SNES and DS versions of Chrono Trigger to accompany my review of the game. Please note that this does not include every change--just the ones I caught. Be warned that this includes story spoilers, though I do split the list up into a spoiler-free area and one full of some story spoilers.

Finally, to get you in the mood, I'm going to recommend you listen to this amazing lyrical(!) remix of Robo's Theme on loop.

Update: I've been corrected on a couple inaccuracies by the Chrono Trigger forum and have removed them.

Spoiler-free changelist:
- The game has been retranslated, and while a majority of the game script is near identical, some of the more famous lines have been changed. Examples of retranslations include the removal of Frog's faux Olde English accent, Magus being referred to as the Fiendlord (and consequently, his army is now simply the Fiends and not the Mystics), and the 12,000 B.C. era being named "Antiquity" instead of "The Dark Ages."
- The addition of the PlayStation's new features, which include the bestiary, anime cutscenes, music player, and treasure guide
- The addition of a DS style combat system, which simply moves the commands from the top screen into the bottom screen, clearing up the screen a bit
- The addition of the Arena of the Ages
- Contrary to what I said on On the Spot last week, they actually did add an extra spot for a letter in character names, meaning you can name the spiky-haired protagonist Chrono if you so choose. Just know that it's sacrilege.
- New items. If you thought Rainbow was ridiculous there's a new sword for Crono that's more powerful and has a 90% critical hit rate.
- The formally missing song Singing Mountain was finally added into this iteration

Spoiler-filled changelist:
- The addition of the Lost Sanctum. This is a new quest hub that appears in both Prehistory and The Middle Ages eras, and is a settlement of friendly Reptites that were not associated with Azala. While I appreciate the effort to add these new areas into the game, the quests are totally pants, to borrow a British term. They're self-contained to the village and the surrounding new zones, and it's just full of a bunch of boring fetch quests. I hope you like climbing that mountain, 'cause you're going to be doing it like 200 times.
- The addition of the Dimensional Vortices. This new dungeon is actually a series of three dungeons that appear, one each in the Future, the Present, and Antiquity eras. Each one is composed of single screen areas randomly stitched together (so it is different each time you visit) from all of the dungeons of the game (and including the same monsters that originally appeared in that screen) that culminate in a unique challenge. For example, one of the Vortices requires you answer four multiple choice trivia questions about the game, and another splits your characters up into two separate groups that must work independently. The final bosses of the Vortices are clones of three of your party members, and upon defeating a clone the original receives significant stat boosts. Also, you find out what happened to Dalton, and he claims he will form the greatest army the world had ever seen in Porre, which further ties Chrono Trigger into its sequel, Chrono Cross.
- An additional ending can be found by beating the game and then revisiting the bucket in the End of Time that originally led to the Day of Lavos. This new location effectively welds Chrono Trigger's notions of parallel time travel together with Chrono Cross' idea of multiple dimensions, and most certainly ties together the two games. You witness the fate of Schala (now the Dream Devourer), and see what is proof that Guile in Chrono Cross really IS Magus and not like, another timeline's Janus that grew up without a crazy mom or something.
