I have no problem paying for upgrades. I make my money building software myself. I'm just stating I'm surprised at the pricing model. Usually expansions are sold at a lower price then the original software. $29.95 for DL and $19.95 for DA would have been more sense (or maybe higher price on the Gold) if StarDock really did value those that bought early.
The "original software" was $44.95 when it was released. It sounds like you would be okay with it if DL currently cost $44.95, DA cost $29.95, and Gold cost $59.95.
Stardock dropped the price of DL to $19.95 and it's been out a year. This is like every other PC game. Stardock release expansion DA for $29.95 a year after original game. This is like every other PC game that was successful. Granted they could have made it $19.95 but they have put alot of development time into DA and they still working on it. That's how they recoup their costs.
Early adopters for PC games always pay more. If you wait a year, you either get the same thing as if you bought it day one for half price, or you get the original game plus an expansion for the same price as day one (expansion for free). This is exactly what Stardock is doing like every other PC game company.
