~12 small interactive activities. The monorail simulator thing, a scavenger hunt type thing, Wii games (lol), Animation Academy, list goes on. It was just going to be an indoor digital children's playground, like Image Works and late era Innoventions with a heavy dose of screens and IP slop poured into it. The coolest part of the whole concept to me was it was being established kinda like how the power strip in Wreck it Ralph was. The idea was that any Disney character could interact with any other one in there, but in a totally non-canon to their franchises way because every character was a digital simulacra version of themselves.
And yeah, all of this was designed in 2018. It would have been pretty terribly dated by now.
