That’s the key here. People who were willing to pre-pay for the game ahead of time are clearly not the target of the DRM, and yet they’re the ones choosing to cancel their purchase. It’s not pirates complaining because they want to play the game for free, it’s people who were looking forward to buying the game.
Having friends and socializing is fun, but I don’t necessarily want to do it for 5 consecutive hours. Even at a party, it’s nice to take a break and let my mind rest for a bit.
