Again, people make mistakes, that includes the employers of the market analyst, and clients of their firms. Remember, all pre-market 'sales figures' are entirely pulled out of the analysts rear end. You can't predict the future, period, all you can do is make a projection based on a bunch of assumed variables, and pushed through some economical baking paper which is asserted to be correct but with no real scientific backing, so 100% of the time those projection models are flawed. The situation is even worse when those analysts are even more far removed from the actual day to day business operations of the client than their own clients board of directors.
It only takes one or two to distribute copies to thousands or tens of thousands, who themselves might make copies to thousands if the buy-and-sell-on notion is correct. The problem isn't the number of initial pirates, but how many the actual pirates sell to.
Wait, I thought the whole point of DRM was to target non-customers from playing the game. If that isn't it, then what's the point in it at all? To stop customers from pirating the game to non-customers? I already pointed out above that, that objective is flawed.
In the past that was true. However now the publishers are turning their sights on the second hand market, and lending to a friend means you lose an activation slot with many of the more aggressive DRM schemes.
Well, until someone cracks time travel, I'm afraid it is. There was plenty of market analysts who were proclaiming that borrowing could expand indefinitely, as did the bankers themselves. It turns out they were wrong, their theories were wrong, conventional wisdom and rational logic was right, and ordinary people again suffered for it because the big wigs were only concerned with their bottom line, and not how or if it would be sustainable. The projection figures are meaningless guesswork, nothing more.
The only way you get meaningful sales data is when you actually sell the product. If it's of sufficient use and quality to people, they'll buy it, and you'll make money. If they don't, they wont buy it, and you lose out. The RDF is starting to spring to mind here... Ah well. That's for another discussion.
