What in the hell is it with game developers and game publishers? Are they just idiots and disconnected from reality? There is a BIG difference between having an online device that is still capable of operating offline (which is exactly how all these "always online" devices they like to site operate) and a device that is still capable of operation, by all the laws of physics, when offline but is forced to not do so for artificial reasons. I can still use my smartphone, tablet, laptop, etc. even when there is no internet connection because there are many operations which do not require an internet connection for the basic operation of entering, processing, or storing data. My smartphone and tablet can STILL PLAY the games even when there is no internet connection. This is completely different from a device that simply ceases to function entirely because it can't connect to some arbitrary server, even when the operations for it don't require use of the server.
If I recall, Adam Orth tried to make the claim that the always-online requirement is analogous to having to plug a vacuum-cleaner into a wall socket. Naturally, everyone saw the error in this logic. Electricity is a physically required source of energy in order for the vacuum-cleaner to perform useful work in running its motor to move air in sufficient volume per time and rotate the brushes against friction such to perform the operation of cleaning by the intake of air. A game console does not physically require an internet connection in order to perform useful work (yes, calculations require work), and, unless it is online-multiplayer only, the game does not require an online connection; even if the game is online-multiplayer only, it does not necessarily require that there be a server as an intermediary to connect between players and manage the game. Plenty of games operate just fine with a peer-to-peer type connection. For this reason, the always-online requirement is simply an unreasonable restriction that only serves to provide inconvenience to the user and questionable anti-piracy benefit to the manufacturer or game producer.
Also, because internet access and stability is not homogeneous and isotropic, there is the danger that any company selling a device that has an always-online requirement for operation will be significantly cutting their market presence. Further, the same company will be opening itself to substantial, overwhelming competition from other companies with similar devices that have no such requirement. This has the imminent danger of creating significant profit losses due to under-performing sales. In a business environment where one is already struggling to remain profitable, engaging in a maneuver that so clearly has the potential to shrink market penetration and sales success is just plain stupid.
TL;DR: An always-online connection is not required by either physics or necessary system design for electronic devices to function. Only electricity is required, which can be obtained in many different ways. Forcing always-online as a requirement for operation significantly reduces the viability of the product and carries an imminent potential for profit loss (you're not getting my money if you do this; I will leave video games entirely, if this is the direction of the industry, because it is not worth the hassle). Only an idiot would actually do something like this.
