World of Light, since its reveal I was so enchanted by it and after completing it, is pretty much everything I wanted from a Smash Adventure mode.
All the sub worlds based on different franchises and the spirit fights, just getting to see what kind of characters were getting representation and a lot of their fights being really cool references to their respective games, was just awesome.
Part of it may be just because I'm a huge nintendo fan, but it was nice to see that all my useless knowledge, familiarity and nostalgia was making me enjoy WoL a ton more.
And the final battle is the franchise's finest moment to me, such a fantastic way to end it.
*Edit: also I played the entire thing with Kirby and I just love to see it as one big adventure where Kirb saves the gaming universe from what amounts to an usual thursday villain for them.
