Wanting to make an Elder Scrolls game when all you can do is write is stupid and will never happen. Having a grandiose dream is great. I too have the rough outline for The Best RPG Ever. Fantasy world with over a dozen sentient races, monsters, factions, different planes of existance, gods, systems, etc. Destructible voxel world that doesn't look like a bunch of cubes (IE: 7 days to die). Economic/army management systems for players who want to become merchant princes/generals, that can also be ignored by those who just want to lop heads off as warriors or fry shit as pyromancers.
I also have lots of other ideas for lots of other games. So I start small, with something I can actually make, finish and publish. Not just because I need money but because the experience itself is valuable if I ever get the chance to make The Best RPG Ever.
