Tech top 10: Top of the PC gaming charts

News.com.au takes a look at the the highest selling PC games bought online for the week ending April 18.

Portal 2

Portal 2 remains Steam's best-seller ahead of its Tuesday April 19 release, The Sims Medieval reigns on Direct2Drive, while Magicka's satirical multiplayer adventure leaps into first on GamersGate for the week ending April 18.

The first three Alone In The Dark games, optimized for modern computers, jump straight to the top of Good Old Games' chart; the distinctively Bourne-esque action of XIII enters in third place.

The Impulse chart has old favorites Galactic Civilizations II and Sins of a Solar Empire occupying pole positions.
