Don't see how that's petty. Releasing games as broken as DC should never ever ever happen, especially for games that cost $60. When next month's NPD comes out I hope MCC is hit with lower than expected sales as well. However, at least with their latest patch, MCC is much better than it was. The online for that game is in a much better state than DC, despite being out for a less amount of time. As for AC, that game has horrible framerates, but at least you can play it still.
And remember DC has so many simultaneous issues it's just ridiculous. No weather patch still, no PS+ edition as promised (don't even want to hear anything about entitled gamers or PS+ is free or whatever else irrational people have to say) on top of the online being broken for people who paid for the game, which is the most egregious problem.
If these poor sales aren't the best possible deterrent for Sony or any other dev/pub to ensure nothing as bad as the DC debacle ever happens again, I don't know what is.
But yeah this will be my last post on this. I just posted because this was the first thread where we got to know exactly what it sold in October.
