Open source and Linux games roundup

Week of February 7 - 14, 2015

Steam Inventory Service beta for Steamworks developers

With an update of Steamworks SDK, Valve has released The Steam Inventory Service beta. This adds another API to the list for Steamworks developers. What this service makes possible is the following, according to Valve:

With this service, a game can easily drop items to customers based on playtime or can grant items based on specific situations or actions within the game. These items can be marked as tradable through Steam or sellable via the Steam Marketplace. Developers can also configure recipes for crafting different combinations of items that result in more rare, unique, or valuable items.

Hats are a good example of such items. They are very popular, as Valve's paid out over $50 million to gamers already who created virtual wares in their games. More on this in an article on Engadget.com.

Mapping Twitch’s massive gaming universe

Ana Swanson wrote an interesting article for the Washington Post this week, about Twitch's massive gaming universe. Twitch is a social video platform where gamers chat, broadcast, and watch videos about gaming. The Twitch team set out to map their gaming universe by using an open source tool called Gephi. The graphs clearly show the most popular games being played, like "League of Legends," "Defense of the Ancients 2," "Counter-Strike: Global Offensive," "World of Warcraft," and "Hearthstone."

Gephi is an interactive visualization and exploration platform for all kinds of networks and complex systems, dynamic and hierarchical graphs. Gephi is a free/libre software distributed under the GPL 3.

Read the full article by Swanson, which includes some of the data visualizations by the Twitch team.

More partners join OSVR

Just after the announcement a month ago at the Consumer Electronics Show where the Open Source Virtual Reality (OSVR) was showcased, Razer announced this week the addition of 13 new partners such as Jaunt and VisiSonics. With these new partners, the total count comes to 38 supporting the VR platform.

And it's not stopping there—the organization is also launching the OSVR Academia Program where it will provide 10 of its Hacker Development Kit VR headsets to universities. OSVR encourages interested parties to inquire on the ‘Join OSVR’ page on the official website.
