I don't see what games with Online have to do with single player games.9. Gamers shall have the right to demand that a single-player game not force them to be connected to the Internet every time they wish to play.
If you buy any game with "online" in the title you should know better. This is nonsense.
I think they are more talking about games like Bioshock than anything else, where internet activation was required despite the game being single player only. I'm not sure why you brought in the word "online".
People often have more than 1 PC, or maybe they want to play their own games wherever they end up. Having to transport the CD or DVD between multiple machines can be a giant pain. For most games there's a no-CD crack out after at most a few days anyway.
