Trails in the Sky to Reverie - S-Craft Exhibition 

Yeah there's over 50 party members spread across across 3 storylines in this game alone.

There is an extra mode after completing the game where you can watch all s- and combo-crafts

I disagree, it looks pretty cool in CSIV. In fact, I prefer the explosive flames that emanate from Berserker's strike, rather than that weird pinkish eruptions from Azure's versions.
