That economic model doesn't work unless a majority of players are happy with the original game. I bought every one of the DLC's for Fallout 3. Some were better than others, but I was willing to take a chance because the core game was playable, without any major flaws (assuming you liked the game at all). That's not the case with Empire. I won't buy any DLC's or expansion until they fix the core game, and I suspect a significant portion of the customer base feels the same way.
