The only new features are a data install to shorten load times and the face load system. Starfish added face load to later Elminage games, which allows players to load images saved on a Memory Stick as character icons.
And there are a lot of character possibilities. Elminage Original boasts 12 races (human, dragonite, dwarf, elf…) and 16 classes (samurai, valkyrie, alchemist, lord… maid?). Finally, a dragon maid for a dungeon crawling party.
