I guess the direction they went with the world made it hard to implement her? Without her just needing saved or something. But I guess it would have been cool if her and Pegasus at least helped some save people in the mean time? That's about all I can think of, other than her showing up with Pegasus before the Rock Titan fight.
But they clearly could have just...changed the structure to fit her in a bit more. Which I would have loved, I have always really liked her, and am always up for more.
I have been busy the past few days so I just finished up Monstropolis. I loved it! It was such a good world I loved the plot, I am glad Randall was involved even though he wasn't a boss. I guess I anticipated as much at this point. There seems to be only one big, important fight per world, which are always really awesome, but otherwise its just large groups of enemies. Which interact with the worlds a lot, so that's cool. I don't mind it per se, but I would love an extra boss or 2. I love cool Heartless designs, and also Disney bosses so you know.
That end scene was crazy tho. Sulley just freaking chucking Vanitas was amazing. And my boys Donald and Goody protecting Sora... So yeah. Not much else I could ask for other than a Randall mini-boss I guess.
