they say its not all that different heres what wiki said:
358/2 Days features the action role-playing game style of the previous games in the series.[10] To accomplish this, the game makes minimal use of the system's touch screen functionality.[11] The game includes single player and multiplayer modes of play.[1][12] The single player mode is story-based, focused on Disney worlds from past games, and progresses in days.[6] In single player mode, the player controls Roxas, the game's main protagonist, who is accompanied by other Organization XIII members.[13] The two modes are linked in that character growth are shared between them.[11]
[edit] Panel system
358/2 Days features a new gameplay mechanic known as the panel system which involves the customization of the character's levels, items, magic, weapons, abilities, armor and accessories. Magic in this game is mainly controlled by this system; certain spells cannot be used if their corresponding panels aren't equipped, but can be used consecutively if multiple are attached. Weapons are also equipped using panels, as well as abilities. There are also "Link Panels" with which multiple panels can be combined to form new, stronger abilities.[14]
[edit] Multiplayer
Cooperative multiplayer was one feature on display at the 2007 Tokyo Game Show demonstrating that players can work together, in addition to the traditional use of AI-controlled partners.[15][16] This is the first Kingdom Hearts game to feature cooperative multiplayer. The multiplayer gameplay is separate from the single player story and will be mission-based, which includes cooperative and competitive player battles.[11][17] It allows up to four players to play as one of the fourteen members of Organization XIII, with each member having different weapons, skills, and stats.[6] Not just the members of Organization XIII, but also, Sora, Donald, Goofy, King Mickey and Riku are featured as secret characters in the multiplayer. 358/2 Days' multiplayer also features a chat system for communication between players, but will differ from PictoChat in that everyone will draw on the same screen.[11]
