do you want to see the first pass Diver: Core Link's rulebook?
Check out the full rulebook here.
BIG EDIT: I have finished the non-play portions of the rulebook (the Play Tips and Building Your Deck pages) and it's now fully done :> At the same link above. Enjoy :D
1. I took Kingdom Hearts and made it at least a little bit more gay and less shitty
When I figured out there was no way in heck I could ship a Kingdom Hearts game and had to gut the story out and write my own… well, I went hard:
Ditch Sora for a grown-up non-binary dork little princet? Check. Black pirate queen whose Keyblade-equivalent is literally a broken coronet that topples thrones? Check. Non-binary xe/xyr cowboy-sorcerer of the salt wastes? Triple check. Polycule? Oh boy why not!!!!!!
Have I done a good job? No idea, the storytelling right now is risible since I am shipping not even one third of what I have designed. But you can see the bones of the thing! And if you play the Light deck, you play with an adorable little fuckboi and their lil weird sword.
2. I think I solved resourcing in an interesting way
Everyone has to throw their hat into the ring of 'let's replace lands', don't they? My take is a meld of several ideas, but if you added tokens to the twilight pool in Lord of the Rings TCG, it may be familiar:

I think the twist was that rather than 'the more your opponent plays, the more you can play' — which is trivially defeated by you refusing to play — it's, 'the more you play, the worse for you your opponent's response can be'. Since you have to choose to either permanently power up your plays or bank XP toward victory every round, it also adds choice points: how aggressive will you be? Can you bait your opponent into taking risks to get to victory faster without having to work to level first?
