I just finished the game last night and to be honest it was like watching the newer Star Wars Movies: kinda hard to deal with since you know how it ends before it even starts, it's just a matter of how it got there. There was only one real HOLY !@#$%!!! moment for me towards the end
Show content
{Where Xigbar sees Xion as Ven (from Birth by Sleep)}
and a lesser one towards the beginning that I only picked up because I saw the additional cutscenes added to KH2 FM+
Show content
{Where they mention looking for two rooms: waking and slumber(?). It's in one of these rooms where Xemnas finds the armor of one of the characters from BBS (and the KH2 secret ending)}
. Those two alone were the things I cared most about but naturally it was more fanservice than anything and wasn't explained at all >.< Still a well put together game and the end did make me tear up but it only starts kicking in around day 277 so keep going!!!
