A dream I had last night inspired this seed of a video-game premise.
It'd be a hack-and-slash RPG where you played a hero who drew their power from three gods: Zeus, Odin, and Isis. You could switch between which god you drew power from (like switching between modes), but each god would grant you different weapons, abilities, and magic spells you could cast. For example, Zeus would give you a sword and shield, stronger armor, and spells like casting lightning bolts or turning invincible for a moment; Odin would give you a big battle ax, stronger attack, and the ability to freeze enemies or descend into a berserker-style murderous rage; and Isis would give you a bow and arrow, superior speed and agility, and the power to fully restore your health as well as summon African animals like crocodiles, lions, and gorillas to help you fight.
I don't have much of a story for this game yet, but the protagonist would be one of two siblings, a brother and sister who shared a triracial heritage (Northern and Southern European through their father, African through their mother). With the help of their three divine beneficiaries, they would fight this evil god that escaped their subterranean prison and wanted to wipe out all the other gods and take over the world.
Dunno if I want to develop this further since I already have quite a bit on my hands right now, but I wanted to throw it out there anyway.
