Okay, So finally the PSP game has been released after 4 years or so since KH2. Right, So with Birth By Sleep it's a prequel set 10 years before the events of the first game. I've now finished the game and it was just as good as the main titles on the PS2, The graphics and style looks amazing for the PSP, Probably the best looking game for the system. The combat is the best it's ever been and it has a excellent flow that gets better and better. I'd recommend playing through and getting 100% completion or beating the game on Hard/Proud mode to unlock the secret ending "Blank Points" since it sets up nicely for the next main game in the series it works similarly to the secret endings from KH1 - "Deep Dive" and KH2 "Birth By Sleep" The characters Terra, Ven & Aqua are very likeable due to the fact they're very similar to Riku, Sora & Kairi, Don't be fooled by Ven's appearance he is NOT Roxas.
Overal great game and hey NO MORE GUMMY SHIP! Finally!
