Obviously the only people that can have palaces are incredibly bad people. But after playing psychonauts stoned off my ass, the concept of got me thinking. Essentially in Psychonauts the gimic is that each level is someone's mind and its up to you to make everything right in their head.
Sounds familiar doesn't it? HOWEVER
Unlike P5, in psychonauts EVERYONE'S mind is explorable which brings the question. What if P5 did the same thing? What if having a palace wasn't limited to people with ill intentions/motives?
And finally, what other way to ponder that than with the phantom thieves themselves?
You can discuss the designs of their palaces, their perceptions of the world around them, what their treasures would be, etc.
But to keep things spoiler free, (and for my sake because I just beat the third palace lol) Let's just leave it at our starting 4 main characters. Akira, Ryuji, Ann and Morgana. SIDE CHARACTERS TOO!!!
