Game Making (MMO)

[Creator]

This isn't the first time I've asked this question, but so far I havn't had much luck response wise.
I would like to know what it takes to make a good game, not too complex that I will never get it done, but at the same time not so basic that it's not worth playing, and what to expect in doing so.
I realise it is a difficult task requiring tremendos effort, but I have no real idea where to start? I've gotten ideas down on paper all over the place, but how do I pull them all together and actually start making the game? I would like to make a MMO eventually but I'm not sure if thats the best place to start.
The other set back is I have no real expirence with scripting, but on the plus side I am eager to learn...

Feedback would be much appreciated
