Pure genius. Thanks for this pearl.
Here in Italy we have a cool, heavily anime inspired, RpG (Knights of the Round Academy) that requires, in the rules, to build the Opening together, usually after the first session.
In the rules we have suggestions about common elements, like:
- world elements
- fast shots on every protagonist
- the enemy/ies, maybe just the silhouettes
- a flyby with main NPCs
- conclusion with some big impact frame
So, of course, this document of yours can come handy 😁
Edit: KotRA is avaiable in English too :)
