I can't "prove" that, because the data isn't there, but it is a completely reasonable guess. At an 8 minute load time it is reasonable to guess there were a lot of people who stopped playing and thus stopped spending because they thought their install was crashed or corrupted, and just silently wandered away. I certainly wouldn't. I've got some games that load more slowly than others but I don't think I've waited multiple minutes since the Commodore 64 era.
