On top of the above statement the expansion packs were not made by 3DR so there is a little more tape you'd have to go through to put it up. Plus they'd probably have to share the costs.

Than you have to consider that adding this content for the game may not be easy as it has to be programmed in which then goes into the category of hiring people to do it and paying them for their time.

It all starts to add up.
