EuroGamer - There isn't one game called Team Fortress 2. There are hundreds. Its famously long development time used to see it compared to Duke Nukem Forever, but that doesn't hold water any more: Duke's finished. The development of TF2 goes on and on: new weapons, new levels, new gametypes, new accessories, new achievements, new features, new hats. All updates are free. And now, so is the game.
