@Sparda's rejected son
You can always watch 358/2 days after you play 2. I'd recommend playing CoM before 2 because kh fans dig that story alot but since Sora forgets what happens (minor spoilers) you could always play it after 2.
No worries I am aware of CoM's ending. I just haven't finished yet. But I don't like CoM/RE:RoN's gameplay, I am not good at its Card mechanic style. So I thought maybe I could simply view RE:CoM's cutscenes, cry, watch 358/2's cutscenes, cry again then jump into motherflippin' KH2 Final Mix! I don't know yet haven't fully decided.
So I bought the super expensive Dragon Ball Fighter Z collection and I have buyers remorse, plus... I kind of thing this game is over rated... Anyway here familiar with the "SuperButterBuns" YouTube channel? God I love her.
