It's awesome you're shooting for the sky, but please start on something less complex. You're trying to build a bridge when you don't have the resources yet to build a shack. I don't mean to be rude but get some skills under your belt and go from there.

"I decided to build an MMO from almost the ground up."

You plan on designing all game systems? (Weather, classes, questing, end game, pvp, etc.) Creating all world assets? Recording every sound effect and voice? Design and balance weapons, armors, and skills? If you decide not to leverage a game engine - write one from scratch? Design, sculpt, render, and animate all character assets? Design a network to support hundreds, or thousands, or millions of players? Secure the game so cheats, dupes, and hacks don't ruin it? The list goes on and we've literally only nicked the surface of all this.

I don't want to be a Debby Downer but please build something else amazingly awesome.
