The fastes selling thing was a PR spin, because they (over)shipped 4.5 Million copies in their first week. They are reporting the sold-in and not the sold-through. The 1st article even has that as a clarification at the bottom:
Beating Mafia 2 is not really a difficult, but do you really think that Mafia 3 has beaten GTA 5 when it comes to that?
Because it didn't.
It's a fact that they specified 5 Million copies "shipped" in their financial call. If that was actually sold, they would be boasting about it. This is also taken directly from the financial call:
Like I said, Take 2 is really bad with forecasts, so it wouldn't actually surprise me.
Do I want it to happen? Hell no. I want the next entry with a powerful story as Mafia 3 has. Just refine the gameplay more and don't give us this repetetive madness. More focused missions, like the takedown missions and they are more than good to go.
Anyways, I think I said it all. Don't want to further derail the thread. I'll still read your reply and accept your opinion on it.
