Well, I tried the demo for a bit....guess I'm glad I didn't purchase this one at launch afterall. I'm a huge Civ fan and am still interrested in keeping an eye on this one, but the negatives outweigh the positives in my opinion (at this point in time), when previous Civ games are already so much fun. I've never been in a hurry to upgrade to the next Civ game, because they've always seemed like more of a graphics refresh than anything else -- sure, a couple of positive gameplay changes, a couple of negative ones. The changes in this one seem very unfocused compared to previous attempts. Maybe it's just not quite finished.
It's also unfortunate the way they are approaching the new DLC method. Sure, everyone's doing it, but the vast majority of DLC is simply not worth the price. You've just sold me black coffee, but you're not even nickle-and-diming me for the cream or sugar. Instead you offer...an upgrade to the default cardboard cupholder???? For 10-20% of the price of the coffee???????? Yeah, I doubt I'd even let you sell me the cream and sugar.
