Just keep in mind that what constitutes the 'best world' is basically just your own opinion.
The most popular game-worlds are all almost entirely developer-created (WoW, Runescape, Lineage, etc). Second Life is a blip on the map by comparison and it has not managed to reach profitability after years of operation. That's not exactly the kind of virtual world I'd be looking to imitate.
