Wow I was actually thinking of starting a thread like this.
I think it could be pretty cool if done correctly, plus we already have the Battle of 1000 Heartless.
Also I made Sora and Terra in Dynasty Warriors 8:
Ah yes, Dynasty Warriors 8: Empires for the PS4, lol.
I bought that one specfically for the character creation feature (as normal Dynasty Warriors-titles or the Legends-expansions don't have it, only
Empires allows character creation), but I haven't got time yet to even
start it.
By the way, did you make those screenshots with the game's features or is that the standard PS4-screenshot feature (which I still haven't figured out how to make it work...<__<).
Pretty certain we had a thread that talked about different kinds of gameplay styles we'd like to see KH have.
I recall as well having such a thread where we even already talked a bit more in-depth about how a KH Musou would work.
One of the "problems" I could see for example is what peons/mooks we could give the "good side" as certainly all KH Original characters and most Disney/FF cameos would be officers.
The Bad guys would of course have Heartless, Unversed and Nobodies as footsoldiers, but what are Sora & co going to get? Spirit Dream Eaters? Magic Fantasia Brooms? Chinese Soldiers from Mulan?
Fact is though a Musou style-KH would be probably the best way to emulate/show off something like a Keyblade War as Musou games are primarily going about mowing through thousands of mooks with flashy combos, kick some enemy officers' asses and fulfill some objectives on a huge battlefield.
Something that is distinct for Musou games is though that depending on the scenario you choose, you can play
all sides. So there would be an option to play as the bad guys and i.e. go with playing Young Xehanort and slash Mickey to pieces in a scenario and therefore I wonder if Disney would be ok with making a KH Musou title.
Going by that, I can see a FF-Musou being more likely than a KH one.
