Wow, is this an unpleasant game to play. So the game LOOKS great. Coming from KH1 remix, basically all of the same assets have been used, with some "smoothed over" cutscenes still from the PS2 remaster. However, basically everything else about this game is garbage. The card combat is clunky and abrasive, even scrub enemies can break your cards pretty easily (don't even get me started on Org XIII bosses...), and the story is pretty dumb. I put the time in to finish the first storyline, but I can't say I enjoyed myself. Maybe I'll play the second storyline and see if it changes my feelings at all, but I'd recommend just catching the story bits from this one in a video wrap-up.

Edit: Went back and played the Riku storyline, and it was good enough to raise the overall rating of this game, but not by much. The story was less than half the length of Sora's, with some good explanatory story bits instead of just "Oh noes my memories!". The pre-determined decks for every world took a lot of the tedious work of deck-building out, but could really suck if you were in a world with a bad deck (Wonder Land). The gameplay overall felt much faster and more dynamic, and reloading your cards with a simple button press instead of holding the button really kept the combat moving. Dueling sucked, to the point I just avoided it entirely, and the final boss was cheap, so it wasn't all roses. I would still recommend just catching the story bits in a video, but the Riku storyline is at least worth playing.
