The only thing that the success of the best-selling 240 MSP games proves is that there is a huge demand for Minecraft-alikes. To say that the best sellers, the biggest revenue generating games on XBLIG are 240 MSP is to simply say that games that drew on a pre-existing fanbase for a particular game are the best sellers. It doesn't make much of a case at all about the 240 MSP.
The fact that the "real" Minecraft came out (on XBLA) and completely blasted away all of the XBLIG craft-alikes in a week pretty much shows that despite the million something revenue of the XBLIG games, the platform is still small potatoes. This particular game style just happens to be really popular.
That said, 240 MSP in the long run was better for CSTW. Once we dropped to 80 MSP on its 1 year anniversary, we got a good amount of coverage and at the same time, a dash ad. Revenue was way, way up compared to the previous weeks at 240 MSP.... For a while. After about 2 or 3 weeks, the revenue income from the period set at 240 MSP is actually higher than it is now at 80. Perhaps the coverage and dash ad was the main revenue driver during that initial period.
What that tells me is that a year after its release, the only people looking to buy CSTW are the ones looking for it, and they are willing to pay 240 MSP. Being at 80 MSP isn't going to grab a whole lot of "impulse buyers" like a first week launch at this point. But we're absolutely not going to raise the price or anything, it's 80 MSP to stay.
As a side note, CSTW sold fewer copies than BODVII but generated far more revenue, which is what we anticipated. It's arguable whether or not an 80 MSP launch of CSTW would have done even more so.
