Otherwise they should be forced to state the game is a rental not purchased if it requires a server that may shut down.
But that is what they already do. Currently this might be hidden in the EULA, that no one reads, but even making this plainly visible during purchase wouldn't change much. I is not like the players have much choice when they want to play that specific game.
A 100-watt bulb is so named because it uses 100 watts of energy for every hour of operation.
This does not make sense. watt is not a unit of energy.
Neither does this:
We’re still nowhere close to a gigawatt, we’ll need 1,000 megawatts to get there. That’s enough electricity to keep the average American home powered up for 100 years.
Valve is the company responsible for unlocking my PC for gaming. Most games can now be played without using Windows and Valve is mostly responsible for that. Because most game developers do not care and would rather force you to use proprietary OS than let you use what you prefer.
