If you aren’t familiar with Steam, think of it as the iTunes for PC games. Instead of buying a physical box with an installation DVD, you can download games directly to your computer. Steam also has its own community of players tools to chat with your friends while gaming.
Once the client becomes available, customers will be able to download games like Valve’s Portal, as well as titles like Torchlight by Runtic Games. The first collection of Mac titles features something Valve is calling “Steam Play.” Steam Play lets customers who have purchased a game on one platform play it on all Steam-supported platforms.
Steam for Mac will add new games every Wednesday. Each new wave of games is designed to showcase another aspect of Steam for Mac. Additionally, starting today, game developers can access the Steamworks’s publishing tools to get games onto the Steam platform. These tools enable game makers to either make their games directly available on the Steam platform or, in the case of physical media games, connect to the broader Steam network.
