Valve is usually thought of as a PC-centric company, though in recent years it's made more of an effort to bring its games to consoles. Even so, PC still managed to be the best-selling platform for Portal 2 when compared with both consoles, Gabe Newell has revealed.

In typical Valve fashion, the first downloadable content pack for Portal 2 -- you know, the game with those offensive adoption jokes -- hasn't come as soon as many expected. Shortly after the game's launch in April, Valve said to expect it this summer. With the season winding down, it's hard not to wonder if that release window still holds up.

One of the best new characters in any videogame this year (or recent years) is, at least in my mind, Wheatley from Portal 2. He and Cave Johnson made for a hilarious cast of characters along with GLaDOS. Wheatley was especially good thanks to the performance of Ricky Gervais and Karl Pilkington pal Stephen Merchant. One Portal fan in particular loved him so much she went as far as to create a Wheatley puppet, the final product of which is nothing short of impressive.

Having fully committed to the Mac, Valve is moving quickly to bring its complete library of games to the platform.

Valve launches a new program whereby gamers can get their own items and avatars added into the game.
