Steam sales are really good for video games. Sure, gamers are making off like bandits as titles dip to prices that are 50, 75 and sometimes 90 percent lower than their list cost; however, all that selling translates to real revenue for game makers, too.

We now have a tool that uses Steam's API and publicly available data to figure out how much revenue these sales actually generate. It's called SteamSpy, and the Summer Sale was its first major event.

The site has a table that's entirely sortable, so that means you can look at the five games that earned the most revenue through the entire sale. You can look at owner count, total sales, deepest discounts, smallest discounts and more here.

The most revenue made in the sale? Total War: Attila with $14,733,246 earned. That's a lot of clams.

Of course, there's a caveat. This is publicly gathered data, and that means a lot of assumptions are made in order to come up with these numbers. From the site itself:

Actual revenue might be vastly different from what is shown because:

  1. There are many ways to obtain a game outside Steam;
  2. Some games are sold in bundles, but displayed here separately;
  3. Prices vary a lot depending on the country the buyer is from.

It's still a lot of money, even if it's vastly different. No wonder Steam does these sales like four times a year.
