We have nearly sandblasted through February's Steam Next Fest blowout before it ends on March 2, so Valve is commemorating the event's halfway mark with official details on what made up its 10 most-played titles. I just… I think there's something a little wrong with the publisher's parameters. According to Valve, Bungie's Server Slam for Marathon counts as a demo.

The Marathon release date is set for March 5, but the Destiny developer is testing its new extraction FPS' strength with the Marathon server slam beta period that began February 26. The idea was to run "a technical stress test," as Bungie writes in a blog post about the event, which offers a sample platter of the game – like a few zones in the Tau Ceti IV colony, access to five factions, and even upgrade trees. I don't think it's comparable to the many brief demos all kinds of developers, including those with far fewer resources than Bungie, have put out.

As Steam Next Fest gets bigger and more crowded with free demos, these developers are still finding wins: "It's kind of early access for Early Access."
