Moderator Action: The discussion is getting a bit close to advocacy of piracy for my liking - posts deleted.
Besides - this is off-topic.

To recap the point I was making in my deleted post: If you don't like steam, that's a shame. You have several options:
1) don't buy Civilization 5. Vote with your wallet.
2) send petitions to 2K. If they got 10,000 handwritten letters, they'd listen for Civ6 (or "Civilization 5: Milking the Fans", the inevitable expansion pack)
There are others, but one of them is verboten (see above), and I'm too lazy to list some of the others.
I'm just tired of how every time a game franchise I love gets a new release on steam, people cry about it, claiming Valve be stealing their data, or that Valve is suddenly going to turn evil, steal their games, and take candy from their babies.

This is Steam's page designed to sell the concept of using steamworks to publishers. One of the things I love about Valve is a rational, forward-looking approach to why piracy is a problem and how it can be fixed:
3. Valuable Platform-Dependant Features
Customers won't want to pirate a game that's connected to 20 million gamers and a feature-rich platform. Features like Steam Achievements, Anti-Cheat, Auto-Updating, and Steam Cloud simply dont exist outside of Steam.
Furthermore, constantly updating your game with upgrades and content leaves the pirates in the dust they are relegated to a featureless game with no community of players.
Compare this kind of philosophy to stuff like Starforce, or to individual games that kind of took matters into their own hands, like the FIFA Manager series. Pirated versions of the FIFA Manager series exist, but they intentionally don't play properly.
Yes, they spent dev time coming up with a clever way to gimp their game when it's cracked.
