Honestly, it's why I think that Universal needs to tread carefully with Pokemon, if they ever use it.
I think Universal needs to play that IP in particular, more closely to a Potter, as it has the legitimate potential to outsell not only Potter, but Nintendo in crowds, merch, and appeal.
They need to make sure that it can be accessible to everyone, but that it can cater to the die-hard fans of the property, especially as there are quite a few ways to do it right.
So you're thinking almost of something similar to the Epcot KP game they did all around the park?
