There's an interesting statistic to be found in a Gamasutra interview with Steam's Jason Holtman, published earlier today. Concerning Team Fortress 2, and just how often Valve feel the need to tinker with and improve the game.
Apparently since the game was released two years ago, there have been 97 updates for the game. 97! That's roughly one a week, and has to be some kind of record.
Sure, that speaks volumes about the commitment of Valve to the game and the ways Steam allows them to directly service their customers. That's surely why the point was made. But I like it because it shows how insanely passionate (not to mention important) TF2's vocal player base is, that their over-bearing presence has Valve so on their toes that they're updating a game on a weekly basis.
