Brave New World is practically CIV VI, though. IT males CiV V so much more enjoyable, fluid and exciting that it's ridiculous.
30 dollar expansion packs are usually terrific by my standard. Usually, you get a similarly sized game for roughly half the price.
There's a lot of DLC I don't buy, even for games I love. But that's not really the point, either. DLC enhanches the publishers the ability to do price discrimination. Take Mass Effect as an example. The people who find Mass Effect to be the greatest game series of all, can buy all the DLC, pay over 100 dollars and get a bigger game than they ever could without DLC.
Meanwhile, players who aren't as crazy about ME can buy just the game, and possibly a few core DLC, paying 50-60 dollars and getting a game as large as - or slightly larger than - what they would have been able to without DLC.
Finally, people can buy the game long after launch, at a low price, paying as little as 10 dollars for the entire game. (This has nothing to do with DLC, but it's part of my point anyway).
Being able to make people who love a game pay more for it is a huge boon both for them and everyone else. If you' think economically, you can get away paying a fraction of the cost - a great boon to consumers - and DLC makes game enthusiasts get more of the game than they otherwise would.
DLC is a fantastic concept for gaming, and while not all DLC is as appealing, the great thing about it is that you only have to buy the ones that truly are appealing.
