Space and laser guns feature prominently in this week's PC sales
charts, last week's consumers opting for aliens and bright-coloured
uniforms over olive-grey outfits and the real world.

Least, they did on the whole. You have to overlook Bad Company 2 at
the #1 spot
on Steam if you want to think sci-fi games dominated the entire
charts. But look at Mass Effect! It's there six times on only two
charts.

June's release of The Sims 3 bested World of Warcraft for the crown of 2009's best selling PC game, according to numbers released today by the NPD Group. Modern Warfare 2, despite a November release, was a strong fifth.

Dragon Age: Origins also saw a November release and also made the top 10, at No. 9. It was one of five games from 2009 to do so in a sector where titles have a longer sales lifespan than on consoles.
