Steam

For a while now Valve have been tweaking Steam store pages, including making them a fair bit wider which is now actually live everywhere for all users.

This was originally available via the Steam Beta Client for Desktop since August, and rolled out in September on Desktop for everyone but now they've also put all the changes on the web store too not just the Steam Client. The pages have been widened from 940 pixels to now 1200 pixels, which may not be huge news but it definitely makes a difference. Especially for screenshots, since you'll see them at a higher resolution now too.

With this change the trailer / screenshot section also gained some new tricks with new viewing modes between a theatre mode and full-screen, with controls to scroll through them that's especially nice when looking over new games to just quickly tap through full screenshots directly.
