When Valve sat down to design its new Steam Community system, it probably figured including the ability to share screenshots would lead to page after page of glorious vistas, hilarious missteps and dramatic explosions.
Nope. Turns out most people currently in the community beta just want to see sex. And butts. And Sonic memes.
The images in the gallery above are, at time of posting, some of (most of them are the) most popular screenshots on each of these respective game's community hubs.
Valve doesn't have a category in its monthly user surveys for "% of teenage virgin internet nerds". And now, it doesn't need one!
Most of these are fairly tame, but just in case you've got a particularly sensitive employer, I'll give these a half-assed NSFW warning.
UPDATE - Thought this was pretty obvious, but not every game has screens like this. You need mature content to take mature screenshots.
