The Complete Edition should include both "Gods & Kings" and "Brave New World". If you are missing both of those, the complete edition may be cheaper than buying them separately.
It would, but I have G&K already.
That gets to what my real beef is - for people who already have part of the bundle, it's still relatively pricey to complete it whether you need one expac ($7.50) or two ($12.49). No real price consideration for those who already spent a chunk of money on it.
Though I think I got G&K + base for like $10 way back when, so it's not like I made them rich, but still. It would cost me almost as much to add the last expansion - like 4 years after release - as it cost me to get the first two parts combined when they were relatively new releases.
[and likewise - HAD I spent $50 on the first two parts, there wouldn't be consideration for that either - I get the logic of pricing that way, I just don't like it.]
