Game Vortex writes: "It's been over three years since Kingdom Hearts II was released. (Let that sink in for a minute.) Now, it appears that it's time for gaming's most successful crossover franchise to get its own sidestory: Kingdom Hearts 358/2 Days. Don't worry about the obscure title or the fact that the last portable Kingdom Hearts game was a card-battler/action hybrid. 358/2 Days is essentially Crisis Core: Kingdom Hearts. The story alone is worth the price of admission, and the gameplay retains most (if not all) of Kingdom Hearts II's strengths and weaknesses."
