As much as I wish I could be excited for KH3 and more KH games, the whole series has kinda lost most of it's appeal to me. I feel like it has been way too drawn out in the amount of time it's taking for KH3, and how many unnecessary games have come out before then. I liked 358/2 Days and Birth By Sleep, but I'm getting reeeeaaaally tired of seeing Sora, Riku, and Kairi's faces. I would really like it if they finally release KH3, then instead of it being the big end, just made an entire new cast of main characters (NOT BASED OFF OF THE ORIGINAL 3) and tried something new.
But I'm sure the games still will be good, KH games seem pretty solid overall. I just lost the hype I once had for the series.
