Like that article points out, I don't think we are the primary audience for all this promotion. And that's something hardcore fans have a hard time wrapping their minds around.
Let's take the folks who were regular contributors here but who have since disappeared. Sometimes as much as a year ago. Does anyone doubt that every single one of them will buy BSI? They were convinced a year or more ago. Whether they still talk about it is immaterial. It's the NEW customers that the promos are aimed at. People on the fence. People who aren't aware of the game. I've seen people avoid buying a game because they didn't know enough about it. I've never seen someone avoid buying a game because they thought they knew too much about it. Gamers complain about not being 100% surprised, but complaining seems to be as far as it goes. They still plunk down their cash (just liked they clicked the links that lead to the videos/articles....) <img />
It's interesting to note that the game was announced due to fear of an eventual leak. Leaks are so common now, nobody seems to bat an eye. Which is a damn shame. And if BSI had been leaked, too, it would have been a non-event. However, by controlling when they announced it, Irrational achieved a rare honor in keeping a game secret for 3 years. A lot of studios can't keep something secret for 6 months. It speaks to the level of loyalty and honor among IG's employees.
