Kingdom Hearts was an amazing game featuring a mixture between Disney and Final Fantasy. You honestly didn't need to know any specific information from Final Fantasy. [Thought Squall name was actually Leon for two years!] This game actually features an excellent storyline featuring Keyholes, Keyblades, and Organizations. [Don't listen to my information, makes it sound bad!] If you own a PS2 or a GBA I would 100% recommend this series!
As much as I love kingdom Hearts, this thread is old news, I mean KH came out when i was like 11 or 12 years old. God i love it. I still play it till this day. I bought a playstation slim just so i can play KH1 and KH 2. It was a good deal 'cause i bought the playstation for 20 bucks! It came with all the components, a controller, and a memory card, although the A/C adapter was a little faulty...
