This is not the first or will it be the last game to fail to deliver on promises, but the game was practically designed to sell around broken promises. The backlash was understandable, and simply more than they expected. My surprise is that the article doesn't read of regret for making poor decisions but more of victimhood like they didn't deserve the backlash.
The biggest thing they didn't consider about is the fact that there's a large subset of gamers that have tons of time but not a lot of money, so the money is incredibly important to them and when they're duped into buying something like that which drastically didn't deliver, they have a lot of time to spend to make other peoples lives miserable. Just imagine how angry these people got.
