Kingdom Hearts II Kingdom Hearts Side-game Idea

I think it would be great if a 2 player Kingdom Hearts fighting game could be made. It shouldn't add to the storyline imo but just focus on gameplay. Sort of like Street fighter, Tekken, MK etc. Really, I would just love to see a 3d fighting game with the camera control and fluid movement of Kingdom hearts 2.

Of course a lot of things from the regular game would have to change for this to even work. I've thought of a few ideas:
-Sora, Riku, Roxas and other possible characters are all given AP and a limited number of abilities to choose from. That way even if the roster is small due to the game's complexity, you are never playing against the exact same character.
-Only 1 round but no time limit.
-4 different bars: A health bar, MP bar, Limit bar/special abilities, and a Drive bar

-MP used for Fire, Blizzard, Reflect and Cure. Basically the same as they were in KH2.
-Reflect still blocks attacks but doesn't hurt your opponent. (That would be crazy broken lol)
-Cure heals X% health based on how much MP you have left.
-If fire or blizzard are used 3 times consecutively, the 3rd hit does more damage and is
unblockable.

-A bar for limit commands and special abilities could work very similar to Street Fighter's ultra meter. When you block attacks or your opponent blocks your attacks, you gain part of your Limit meter. You could save up and use the whole bar for a powerful ability like Trinity limit or use part of the bar for an ability like Ars Arcanum.
-I'm not sure how the Drive bar would work, but drives definitely have to be toned down a lot.

-Techs from KH1 are a must. If you block your opponents first attack of a combo at the right time, you knock them back and can quickly hit them.
-Combos can't just be button mashed. Somehow, skill needs to be involved to do more damage to your opponent when attacking.
-Just like regular bosses eventually escape attacks, you should have a chance to escape your oppponents combos at a certain point. (Maybe through a well timed reaction command).
-Arenas could be various places throughout Sora's story. They would all have to be fairly small so that people aren't constantly gliding away and wasting time.

None of that has to be set in stone, just my ideas lol. This topic may have been discussed before and it might not even be possible, but I'm just throwing it out there because it could be really cool. What are your thoughts?

 

I would love to play a game like this, sort of Final Fantasy Dissidia style was the way I imagined it. It would be cool for all the characters to be included, like all of Organisation XIII AND Terra, Aqua and Ven. It would be impossible but I wouldn't think that would matter if it's just a side game with no development to the story. I do think this type of game would work really well.

 

I think it's a brilliant idea. I'd personally enjoy beating the absolute crud out of Sora as Demyx. I can just picture myself yelling at the screen "WHERE'S YOUR KEYBLADE WIELDER POWERS NOW?!" XD

 

I like your view on this. It would definitly be a great arcade game. Make the battle system more dynamic and epic than the regular series, except after this game is made the actual series would still use it's regular fighting.
