I agree with all your other points though.
For about a week, the game simply wouldn't connect to varying degrees. The really frustrating thing was "connecting" happens like 5 times before you actually get to game play which means you can fail at the launch screen, the play button in the second launch screen, or the "claim city" button in create a city mode. It also just might die mid game or your city might be "corrupted" and become unplayed (happened to me). If you're unfortunate enough to have this happen and need to switch "servers" you not only lose your city (it's tied to the other server) but you also have to play or at least start and exit the tutorial. Which btw, introduces a few other points of "unable to connect" possibilities.
I've spent more time trying to get past each of these connection barriers than I have playing the game.
That's a really big problem
Tell me, If I go to the SimCity forums will I see hundreds of people complaining about a game that doesn't work? If I go to YouTube will I see videos of buggy behavior and reviewers irate about the state of the game?
That too, is anecdotal evidence. But, since you're only worried about data, I guess the larger amount wins out. So, clearly, the data indicates the game has issues.
