I've been wanting to create a role-playing game for a long time. I've had tons of ideas but I haven't been able to turn those ideas into something real.
I've even thought of different kinds of stories and game possibilities occuring in the same universe, kinda like World of Darkness, but again, I don't know where to start.
I usually start by defining the different kinds of characters and the abilities they'd have, but it's always so empty...
Where should I begin? How should I begin?
edit for making the question less broad:
So far, I've thought of a fictional universe and a story explaining the reasons why such universe exists in the first place.
I've thought of a multiverse coexisting in the same plane, and worlds in them; how they are different from each other and how they are alike.
I've thought of different types of characters, abilities, political systems and the world where a new character will start.
I've thought of its history and the background of the different types of characters, their defining features and specialities.
But once i've defined the major plane of existance, the world and the broader things, and then the classes and stuff, I get stuck. I have all this information but i dont know how to put it together and make something out of it.
PS: sorry for bad grammar or language mistakes, but english is not my mother language.
I mean, after I've defined those things, I'm like "okay, lets make a character sheet" but then i feel like theres no way the things i imagined can actually be placed together to make something nice or even decent. It ends up feeling like a bad copy of D&D or WoD.
