Why would we lie to you? What's in it for us? Why do you think we work against you? (Please don't answer those, they are rhetorical questions)
If I say that we didn't change anything, then that's what happened. You can't predict the exact number of fans on the next game because there are too many things that affect it. And yes, we want to keep it that way, it's designed that way, it's part of the game. If you knew how everything works, the fun part of the game would be gone.
I guess admitting that your theory (that we changed something) is wrong is out of the question, so I'm going to say this: I can't prove to you that we didn't change anything without showing you the code (which is out of the question) so you'll just going to have to trust me on what I say. I'm here to help you and I don't arbitrarily choose on opposite opinion and lie, I base my statements on facts.
Bear one more thing in mind: I will not let this thread become a long discussion.
