Kotaku PC Sales Charts: Probing Uranus

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.

The story is too old to be commented.
