Dead End Thrills, a great site for your downtime/wallpaper needs, is a bit of a favourite of mine. And for good reason.
They take screenshots very seriously, turning them from promotional tool or keepsake into art. And not just the kind of art that you just stare at. The kind that's a little more practical, that you can also turn into wallpaper.
Some of the game's you'll find in this gallery include Portal 2, EVE Online, Mirror's Edge and Modern Warfare, though you'll of course find a ton more at the link below.
To see the larger pics in all their glory (or so you can save them as wallpaper), right-click on the "expand" icon on the main image above and select "open in new tab".
