Holy shit...
I'm actually hyped for KHIV.
That looked incredible. You know, it really reminds me of what I expected KH2 to be after the Another Side, Another Story trailer. The juxtaposition of the surreal fantasy elements of KH with the incredibly stylistic photo realistic graphics Square Enix is known for. It's glorious. The way the Darkside Heartless translates into a more ominous and demonic kaiju disaster in a metropolitan battlefield was just... Wonderful.
Streletzia looks adorable and Sora looks cool too. The whole vibe is just perfect.
As for what came before it, I'm not interested.
But I will say, it seems like they're remaking Union X so it doesn't look or play like ass. Which is good, I suppose. Nice use of the KH3 assets!
