Keeping in mind what was already said, they wouldn't incorporate anything that would butcher the game's lore, what would you all like to see and how would you like to see it implemented? And if you don't want to see it again, why not?

I know a lot of people didn't really like the LRFFXIII event, but I really did enjoy it. It was pure fan service, but I'm honestly okay with that Anyways, I think it would be cool to see some bosses or maybe monsters from previous games appear somehow. I also love the idea of gathering outfits/weapons from various games, but I can see it being problematic if everyone is running around dressed up like Squall.
