lol, what a topic!!!
Anyways... an RPG is not that difficult ... to a person that can gather all the ideias. You gona need not a pc but lot of paper and a pencil. Turn off da PC to save energy and some $$$.
Get a place to work and start to write all the ideias for da game. But it must be ALL the ideas, even if you plan to to put a fly on the screen. After this task (it could take weeks or months) you can finelly organize all the papers and write the development document.
Why it is necessary? because it contains all the information about the game. Metal Gear Solid 2 had a 300 pages development document and it looks like my C++ book! but normally you don't reach that^^.
After all this, you can start to make the game. If you don't do this you'll waste time thinking "what i'm going to work today?" or "what i'm gona do next?"
That's mistakes that i normally do ^^ so learn now and don't do mistakes then.
If you don't have any idea how to make an RPG install RPG Maker XP on your pc. Make a simple game or download it and see how it's structure.
Good luck, impossible is nothing
