Kingdom Hearts 2 is AWESOME! End of conversation.
For me this is the best in the series probably till Kingdom Hearts 3 comes out.
I started playing this because a friend of mine had it and showed me it, and I thought it was pretty cool, but he was apparently stuck and didn't know what to do, so i borrowed it and see if i could find out what to do.
After playing for a few days and still not knowing what to do, I started again to see if I could find out like that, and that's when i became submerged into the amazing game of Kingdom Hearts 2.
I discovered Sora's story and what he was trying to do and why. I also learned a great deal about friendship oddly enough from this game.
The gameplay is awesome, with the great but sometimes annoying limits you can do when you near some companions.
There are also the Drive forms which were a great deal of help during battles and boss fights, including the secret FINAL FORM that is optional but you can also unlock it by accident like i did in my second way through.
I was never a fan of the Summons i never used them, i only leveled them up in the end to get closer to 100% completion, still didn't use them after that.
The Gummi Routes aren't bad either, 1 or 2 of them are complex and annoying, but awesome all the same.
The fact that you can SYNTHESIZE your own equipment is also very cool, the shames is the only WEAPONS you can synthesize are : Ultima Weapon, Save The King and Save The Queen, the best in the game.
You can only mainly synthesize armour, rings, items or more materials so you can make other stuff.
The introduction of Nobodies was also a key concept into creating KH2 otherwise the whole game would go down the toilet.
I played this game to the fullest and got 100% in Jiminy's Journal ( it tracks everything you do , if you didn't know this before)
I think i've wasted enough of your time now, so goodbye.
