6. Kingdom Hearts
The revolutionary hybrid of Final Fantasy and Disney, Kingdom Hearts was a wildly popular game when initially introduced on PS2, thus leading to numerous spin-offs that have stretched the story as far as humanly possible, all eventually due to culminate in the much anticipated Kingdom Hearts 3. Remove the justified bitterness though and the original Kingdom Hearts was a great game. Not only did it have an interesting story in itself, but it was chock full of numerous add-ons, such as the 'Gummi Ship' and a wide range of not-so-secret bosses. However, that's where its biggest flaw lies. The Gummi Ship was a tiresome mini-game in which you had to navigate your way through various obstacles to clear a route to a new world. The context fit, but the execution was poor. Gamers were encouraged to collect items and break records in order to power up their ship, a theory that was beyond optimistic. There was also a plethora of items that could only be gained by a slim 5% chance when defeating an enemy. The replay value was poor, due to the repetitive nature of this mundane task. The reward though? The best weapons. However, these weapons required the rarest of items to create, thus the chances of getting said items were ridiculously small. They required hours upon hours of gameplay and a whole lot of luck. I'm not even over exaggerating.
