Allo, I think I used to do this once upon a time. This whole reviewing games thing and analyzing.
So Kingdom Hearts 3, or Birth By Sleep, is the recent PSP offering. It follows the story suggested by the hidden movie in Kingdom Hearts 2 all those years ago. It's a movie you'll see lots of times, it being opener and closer for each of the three stories, as well as the standard demo movie on the title screen. It almost makes a very neat plot weave with the other games. It almost makes a very nice mechanical build.
Almost is more a good description of it, but not quite there. The game has six real worlds, a tourney, a mini-tourney, a minigame center, and a few narrative story worlds. It's got a pretty stellar take on monopoly, a cruddy volleyball game, a weak mario kart, and combat.
and I'll continue this later.
