No, I don't think that's quite the same thing. The difference here is that BNW is, essentially, an upgrade to G&K. The primary issue here isn't that they were purchased separately, but rather that the subsequent purchases include material for prior purchases. I don't go away and buy the Gold edition, for instance, because I'd be paying for stuff I've already bought. However, when the upgrade to my existing game comes prepackaged with such material I'm effectively paying twice for the same thing and the option to avoid purchase of already purchased material is not there. G&K is already a prerequisite to play BNW, what's happening now is that they've just decided to bundle G&K with BNW and not differentiate between those who have already purchased G&K and those who have not. Speaking solely to the BNW features - yeah, it'll be worth every penny. I've been supporting the Civ series since the original and I've yet to be disappointed with it (even Vanilla Civ 5 was bearable... kinda). I suspect a great number of others feel similarly. However, what OP is getting at is how someone who purchased G&K must pay the same price for BNW as someone who did not purchase G&K despite the fact that the latter is also gaining the G&K features for free. Personally, I'm on the fence about the discount or some kind of G&K prerequisite. I reckon either would be a good move to reward loyal customers. On the other hand, there would obviously be a cost involved of lost earnings that 2K/Firaxis would be unlikely willing to bear and they'll risk alienating any potential new customers who might come across BNW when those new customers realize that they have to purchase a different expansion pack to get what they actually want. There's also the more general point to be made that, irrespective of what 2K/Firaxis decide or what we think of their decision, we'll still buy their stuff. Why? 'cause it's Civ. This is... I mean like really. If you're going to use metaphors at least make them so that they support your own argument. You already get a discount on purchasing an iPhone 5 if you have an iPhone 4 by trading it in, this has been common practice in the mobile phone industry for years.
