Obviously KH hasn't been completely forgotten, but the level of enthusiasm is now limited to a fairly small core fanbase. From reading the thread, people seem to be blaming the long wait for KH3, but that game still managed to be the best selling game of the franchise up to that point. That's because of how insane the hype was leading up to KH3's release, where even ecelebs who gave zero shits about the franchise were weighing in on it. So the question is "why isn't it the same for KH4?" I think the answer has more to do with the complete lack of information fans have gotten about KH4 so far. Even if KH3 was a disappointment, Square could have maintained the hype train by showing off how KH4 is going to be much better. But so far, we have seen so little of the game that fans have to zoom in on blurry back ground objects in the trailer to generate any kind of hype. And yes, there has only been 1 trailer in the 3 years since the game's announcement. In comparison, KH3 was announced in 2013 only 1 year after KH3D's release, which already set up the conflict in KH3. In 2015, we had trailers for Olympus, Tangled, and Big Hero 6 worlds. Square delivered at least one trailer a year and a steady flow of updates to keep fans excited for KH3.This also included updates for the mobile game as well as a sort-of demo for KH3 in 2017 with KH2.8. In contrast, since KH4's announcement, we have seen the mobile games removed from the app store, the cancelation of the next major story title, 1 trailer, a few static images, and no confirmed Disney Worlds. There certainly are plenty of other problems I can think of too, particularly with how the mobile games made the story even more complicated without resolving much of anything. But I really do think that Square could have maintained hype by showing off the next game. But the fact that have shown so little makes me believe that they still don't have anything to show.
I now dedicate this thread to Indiana Jones anon. God Bless.
