Well, we are changing things, just not in pursuit of a particular game mechanic or with the purpose of shifting the balance in favor of a certain vehicle. New information comes to light, we revise numbers. After a thorough check. Both other game developers and us do commercial software development. But given the different nature of revenue streams, we can afford to maintain independence from the preference of a certain user group, or investors, and it turns out that for professional usage purposes, trying to remain neutral and realistic is the best overall strategy.
Of course, we're still operating in an environment where a good part of some information is classified, so we have to offer our best guess. But then again we don't claim that you'll get The Truth from Steel Beasts, just something that is sufficiently plausible and fit for the purpose.
