Having played The World Ends With You/It's A Wonderful World last semester, I'd like to see another game that uses the split screen battles in the same fashion. Controlling two characters in separate rooms, fighting the same enemy (sometimes on both screens, sometimes switching between the two) was an excellent challenge. Fortunately, the player could leave the second character to an AI when necessary. It's a mechanic well suited to Nintendo DS and potentially to PC games as well. Even forcing players to share the same healthbar made battles much less forgiving.

Also, clothing required bravery to wear and gave stats boosts based on local brand popularity. If only all armor and weapons required as much thought. Synchronization boosts and timing penalties certainly had me paying more attention to my characters than then repeatedly clicking the enemy. A fantasy adaptation would be difficult, but not impossible. So long as the villains say "Prepare to be spicy tuna rolled!", I'd enjoy it.
