We seriously can't help ourselves. Every time Steam has a summer sale, or a holiday sale, or any other type of sale, the prices go down, and our bank accounts follow. Though not by much, at least, since the games often drop to mere fractions of their normal prices.

The downside, though, is that we have dozens and hundreds of games in our Steam libraries that we simply don't have the time to play.

Now redditor LambentStew has designed a handy tool that will calculate just how much you've played all your Steam games—and how many of them are collecting virtual dust.

We've never felt more frivolous, but how are we supposed to turn down the entire Valve catalogue for only $75? Come on!
