Regarding Days, KHII's introduction is fantastic.

I too have talked to several people about KHII's introduction, and I've realised that there are two kinds of KH players: Those who play for the plot and the others who play because of the series's gameplay.

First group would of course also enjoy the gameplay, however they are stunned due to the storyline, the characters, the music and so on.

The second group would very likely keep skipping videos, fight every opponent they come across and casually follow the plot. And maybe they'd like the game for the "Pirates of the Caribbean"-world because they're like "OH MY GOD LOOK IT'S JACK AND 'HE'S A PIRATE' PLAYS IN BATTLES".

Your two friends would seem to apply to the second group, people I'm disgusted with.
As for my share, I think I'd find myself in group one.
