*shrugs* Wouldn't they then be willing to make more money off more of our free labor?
I mean, this is why I'm concerned that they oughtn't be allowed to cut up the main quest and say LA LA LA EXPANSION PACK MONEYPLZ! - the players have already paid to be allowed to play a game all the way through, but as has been evidenced on Graal's competitors, players are more than willing to shell out half-again as much as they paid for the original (or $10 more on FFXI) for an expansion that only offers them more areas, more stuff, more races/options.
If Kingdoms sold a $10 expansion pack that let you play as an orc with completely different stats from a human, it unlocked the orcish mudhut model (though you still gotta build it yourself), and unlocked the Orcish Homeland, how many people would buy it? I don't know, but given the excitement that City of Villains generated, I'd say a fair percentage...
