I'm on media blackout right now. I am glad they haven't spoiled the entire game through trailers and video features. Only showing the same few parts and refraining from giving it all away.
I'm still hyped for it, and after playing the demos, I'm confident what they're going for will be fun, gameplay-wise. The Duscae demo didn't sell it for me at first, but as I delved deeper into it, I ended up asking for more.
In any case, I'm waiting for september 30th so my Ultimate Collector's Edition finally arrives. The movie looks phenomenal, the game looks better than anything that's been released in the franchise since FF XII, and I welcome the gameplay changes they're going for this time around. I'm not really concerned about the gameplay changes from title to title all that much. I know a lot of people wish the series had remained to the ATB systems of yore, but I really don't mind a more action oriented battle system. In fact, for all the flak FF XIII received, I actually quite enjoyed its battle system, even if it was quite different from what had come before. Although the rest of the game... Not so much.
But FF XV seems to have an interesting and intriguing story, great characters with good interactions between them (unlike FF XIII), and gameplay features, like airship, chocobos and overall exploration seem to bring back a lot of the stuff that went missing after FF IX.
So yeah, Final Fantasy XV is currently my most anticipated game this year.
I don't think the hype has died or anything. I think people are just now waiting for the game to finally come out.
