I have no idea where this is likely to go, if it goes at all, but the idea struck me and I figured it couldn't hurt to try it out. This is basically going to be something of a combination of Chose Your Own Adventure and an RPG. I actually would have put it in the RP section, but we no longer have a section for Fantasy, so here it is instead.
The way this works is simple enough. First, chose some fantasy race: elves, orcs, dwarves, trolls, or just vanilla human. Then choose good or evil. Thus will your godly avatar be born, and you will be given choices with which to influence your chosen race. Some will be simple yes/no, others multiple choice, and some open ended. Your choices will influence how well, or poorly, your worshipers' society fairs.
At first, your power, though mighty by mortal reckoning, will be limited. You will gain power as you gain worshipers, or as you devour souls, or both. With greater divine might, you will be able to perform greater acts, and your scope of influence will spread.
Behold the Elemechnicia, the engine of creation. From this cosmic machine, all that is, all that was, and all that will be to come spawns. Within its infinite dimensions, all matter and energy, all good and evil, all that is mundane and divine is created, matured, and set free to shape and reshape the fabric of reality.
A new Cycle has begun, and divine energy flows to the World Core of the Elemechnicia. This planet is the nursery of the gods, and all new divine beings mature here before seeking their place in the greater multiverse. The Core teams with mortal life, ready to give up their prayers and souls to nourish the godlings, for that is the purpose of their existence. Upon the infinite surface of the Core, the godlings will cast their influence, and they will shape and be shaped by the World. They will encounter matters mortal and divine, from the cares of their worshipers and wars, to the immortal husks of failed godlings and eldritch abominations that feed upon the divine like parasites.
The Cycle begins.
