This is Final Fantasy returning to it’s classic turn-based formula, while at the same time also trying to take a stab at the monster collecting genre. To prevent clutter during battle, a new mechanic called stacking was created for the player characters to fight alongside their monsters (known as mirages). There are also summons called Champions -- chibi forms of famous Final Fantasy characters which are summoned temporarily, including Sephiroth from Final Fantasy VII and even Sora from Kingdom Hearts.
The story of the game isn’t quite as interesting as other Final Fantasy games, but a revelation near the end of the game about the main characters might surprise you. At times, the game can be pretty boring, and as much as using the fast forward function helps in battles, sometimes it doesn't feel quite fast enough. Part of the last dungeon can be pretty frustrating too, due to lack of a proper map.
Despite its few pitfalls, World of Final Fantasy is not only a great alternative to Pokémon, but a great start for anyone looking to play a modern Final Fantasy game with more traditional gameplay.
