Money and scale, yes.

So why not make it a distributed database?

That way all the resources are provided by the players (and ISPs,

Then it's not a money issue.

BerkleyDB (underlying MySQL) is available gratis for Open Source
projects.

And you don't need to sell the database to sell the game. Give away
the database. Sell the content.
