Nostalgia is powerful force. Square Enix is aware of this and banking on fuzzy childhood memories is one reason why Final Fantasy Dimensions is getting so much attention. A new job class in the iPhone/Android game is a master of memories, but Argy starts the game with none.
If Argy has any memories he would be over powered. Players can search for memories (small, lovely, and important) to boost Argy’s parameters like strength and speed. Argy’s battle command "Memorandom" uses a random ability Argy learned, which gives players access to a larger (although random) selection of skills.
Final Fantasy Dimensions uses Final Fantasy V’s job system where you learn new abilities by gaining AP. You can equip learned abilities even if you change jobs to create a Ninja with Black Magic or a Dragoon that can Dance. With careful ability planning, it sounds like you can make the Memorandom the strongest skill in the game.
