Final Fantasy 3  

Alternate Endings 
In the World of Ruin, don't get Sabin, Locke, or Strago, and get Relm but never 
bring her to Kefka's Temple. When you beat the game, the Figaro's, Celes's, and 
Relm's endings will be rather different than normal. 
Level Up Trick 
In the World of Ruin, only get the four initial characters (Celes, Sabin, Edgar, 
and Setzer). Get the falcon, and fly to the forest where you fight the 
Tyranosaurs. Bring you characters to the level you desire (don't forget to use 
the Exp. Egg to help you out), and then get the other characters, and they will 
now be at that level.
