EDGE online makes note of an inquirer article commenting on how it seems HL2's offline mode is still requiring an online connection and that none of this HL2-Steam enforced connection is obvious from the packacing:
Also:"More interesting, perhaps, are the legal agreements that surround a purchase of Half-Life 2. One is that no mention of Steam is on the HL2 box or in the End User License Agreement, yet it is required to play."
Finally, the author concludes with some inspiring hate:The German Consumer Association has recently found that the packaging on Half-Life 2 is misleading. In a report made following complaints from the public, they said that the mere listing of an internet connection under the 'other' category in system requirements did not accurately describe the true extent of the internet tie-in with the game, and ordered Vivendi to amend the packaging and untie Steam from HL2 or face a hefty fine.
"So what's the best course of action? Well, as always, it's to get people with lots of money to go after Valve. The Germans have already done it. If you're really annoyed at Valve for the whole situation, organise some mates and complain to your country's consumer association to get something done. You'll find they're surprisingly receptive to things like this."
