In Chrono Trigger, there will be new opening and ending cinematic sequences, as well as recreations of existing sequences. The new game modes will include a theater, music box, and an art gallery that will open up as the game progresses. Detailed descriptions of the monsters, magic, and bosses are also included. (kinda like Final Fantasy Anthology)

As for Final Fantasy IV, you can now dash through the towns, dungeon, etc. There will also be a FMV in it as well... And the best new change to this game is that it has a new two-player mode that let's two players participate in battle together!
