I only finished the Lucky Emblems...but I was sorta cheating(I was watching Soraalam's guide hahaha)

I guess it was the battle gates seeing as the last trophy I needed to platinum the game popped while I was going through all the battle gates.

The whole game leading up to the Keyblade Graveyard was the longest side content it took me to complete.

I only really completed the Lucky Emblems by consulting the internet. I’m at the last Battlegate, but have yet to complete it.

I'll say the Flantastic Seven. I never did get far in the cooking mini game so I never completed it.

I’ve actually only completed Lucky Emblems and it probably felt longer than it actually took as even though I was using a guide trying to get to the actual locations could be a bit annoying at some points especially In the Pirates of the Caribbean world. Although I have done a bit of everything else and there a lot more fun than searching for Lucky Emblems in my opinion.

Probably the Lucky Emblems. I spent so much time looking around for them that I started seeing Lucky Emblems in the real world as well! Ended up cheating but I found about 70% on my own.
