How come so many of these sales related discussions turn into arguing about game financials, without much real knowledge of a) the game development budgets b) game marketing budgets c) publisher/dev/manufacturer profit margins and finally d) corporate financials and accounting?
@Kantor
Your question is pretty much meaningless if you don't consider the development costs, marketing costs and profit structure. Sure, 20k more sales MIGHT bring in more revenue, but that does no directly translate into more profit.

What you are not understanding is that, in reality, GeoW cost way more to make than what 250k sales bring in. However, the engine development costs were written off to another projects, probably a wholly separate engine project the costs of which were not accounted in the GoW project. The fact is that we do not know the real cost of making GeoW, and it would be hard to determine anyway since the engine is done for licensing, not only for GeoW. Any game developer developing a similar game in-house would have to develop the engine and add the costs to that game, resulting in much higher costs. To put it in another way, it would be nigh impossible to develop a GeoW-clone so that it would break even with 250k sales.
