Something only Duane Johnson could accomplish.
It was a genuine question. What precisely do you mean? Because I mean, several million (last I heard was 7) people are playing League of Legends at any given time. Never mind the concurrent connections for huge sites like Google and Facebook. Never mind where you get the numbers. Why is 1 million people (where does this number come from) being placed as a huge task? Is it? Based on what? Your past experience? It isn't that difficult to think of examples that countermand this, including the launch of SWTOR (which would have much greater server demands). Sure something like SimCity had issues, but again the demands on the server won't be the same.
Please drop the flippant answers in the future because they are not necessary and come across as deliberately evasive (i.e. you have no basis for your statement). Given your previously established position of not liking the Keep solution in general, it undermines your concerns because NOW I think you're just rabble rousing because you want people to believe your statements so that they will reject the Keep. Unless your goal was to simply aggravate me, which I suppose we can say "mission accomplished."
I would expect DA:I will be your best opening week for the DA series. Possibly for the company. I'd be, frankly, astonished if you didn't break 3.5 million over the first six weeks. Maybe more if the game is well received.
There's a mountain of difference between inciting concern because of 3-5 million people concurrently and you expressing your surprise that we don't break 3.5 million in six weeks. I'd also be surprised if the game wasn't that successful over that period of time. But unless your point is that people will stay on the Keep 24/7 for several weeks why they're playing, it doesn't seem particularly relevant to your point about overloading our servers.
