It's funny I was thinking about making a topic about this same issue in Data Greeting. I love it to death and it has been my favorite part of the ReMind DLC so far but I too noticed the lack of Disney characters and the lack of iconic location in the worlds. No Andy's Room, Scare Floor, Elsa's Palace, Rapunzel's Tower, 100 Acre Woods, Olympus, or San Fransokyo. The Disney characters also bugged me. Not even Maleficent, Pete, Minnie, Daisy, Pluto, Merlin, Chip, Dale, Jiminy and Yen Sid made it in
I also agree with the lack of sitting poses. I said this in another thread but I wish Demyx, Vexen, Aeleus, Dilan, Ienzo, Ansem the Wise, MoM, and the Zoo-Keys (Foretellers) also had models to use as they would have been fun too! And also as said above alternate Organization member outfits. Dark Riku, Vanitas, Ansem SoD, and Terranort all have portraits with their coats on but not a option to use them. Likewise Roxas, Axel, Xion, and Saix all have alternate Twilight Town clothes now. It would be amazing to have their change of clothes to pose with too.
I know they said DLC for KH3 is done...but maybe they could make a free patch to add some of these things? I know it's a hassle to get the Disney characters and locations but what about all the OG stuff for the other characters? I love Data Greeting and would like more freedom with it. Am I asking too much?
Edit: Almost forgot Eraqus, Lingering Will and the TAV armor forms. I wanna pose with them too! I want more!
