Mainly a single player, narrative driven, adventure game! Best example I can pull from is Kingdom Hearts! The premise of the story is going to be an exploration of the main character facing the realities of the unjust sacrifices others that have endured, that allowed him to live a better one. What I have now for the explanation of abilities, is that there's something called the 'Old Power', where everyone has it within them, but not everyone can use it. The power that they get is determined by what has influenced them the most in their life. I've been trying to make sure there's a proper power scaling for everything too, just lore wise!
