Final Fantasy Origins
The two-game collection that almost completely remakes the original Final Fantasy, and the formerly Japan-only release Final Fantasy II, Final Fantasy Origins for PlayStation One is one of the most in-depth Sqare remake collections yet. Revamped graphics and added event scenes further engross the player in the emotional storyline. Saving is no longer restricted to certain locations with the addition of the Memo File function. Multiple gameplay modes allow players to customize game difficulty when beginning a new quest. CG movies and stills have been added throughout the game, taking the story to new cinematic heights. Improved sound quality, new opening themes, and an added art gallery deepen the game experience.

Final Fantasy Origins was most similar to the WonderSwan Color remake (made seperately in 2000). There were only minor alterations made to help take advantae of the new hardware, higher screen resolution, and raphics that Sony provided on their console. Here is a list of some of the new additions:

• Remake of two Squaresoft titles that laid the foundation of the Final Fantasy series.

• There is only one available Blood Sword, while there were 2 in the earlier versions of the game.
• New Soul of Chaos dungeon (FF1)
  The dungeons are accessible by bringing power back to the Crystals by defeating each of the Elemental Fiends. Following the defeat of each fiend - a dungeon unlocks, terminating in a selection of four bosses each from Final Fantasy III, IV, V, and VI.

  A bonus storyline called Soul of Rebirth is accessible, featuring a number of characters who had been killed off during the course of the main story. The game only features four areas and most of the time will be spent training up for a second encounter with the last boss.
